Anti-Obesity and Anti-Dyslipidemic Effects of Salicornia arabica Decocted Extract in Tunisian Psammomys obesus Fed a High-Calorie Diet.

Salicornia is a halophyte plant that has been used in traditional medicine for the treatment of scurvy, goiter, and hypertension. It is commercialized in Europe and Asia as fresh salads, pickled vegetables, green salt, or tea powder. This work is the first to assess the potential anti-obesity and anti-dyslipidemic effects of Salicornia arabica decocted extract (SADE). SADE was characterized by its significant in vitro radical scavenging activity (using DPPH and ABTS assays). The effect of SADE on food intake, weight loss, serum biochemical parameters, liver and kidney weights, adiposity index and on liver histology was investigated in the Tunisian gerbil Psammomys obesus (P. obesus), which is recognized as a relevant animal model of human obesity and diabetes. P. obesus animals were firstly randomly divided into two groups: the first received a natural low-calorie chow diet (LCD), and the second group received a high-calorie diet (HCD) over 12 weeks. On day 90, animals were divided into four groups receiving or not receiving SADE (LCD, LCD + SADE, HCD, and HCD + SADE). If compared to the HCD group, SADE oral administration (300 mg/kg per day during 4 weeks) in HCD + SADE group showed on day 120 a significant decrease in body weight (-34%), blood glucose (-47.85%), serum levels of total cholesterol (-54.92%), LDL cholesterol (-60%), triglycerides (-48.03%), and of the levels of hepatic enzymes: ASAT (-66.28%) and ALAT (-31.87%). Oral administration of SADE restored the relative liver weight and adiposity index and significantly limited HCD-induced hepatic injury in P. obesus. SADE seems to have promising in vivo anti-obesity and anti-dyslipidemic effects.

Distribution of Salicornia brachiata and Other Halophytes along the Estuarine Habitats of Bahuda River, Ganjam District, Odisha

Halophytes including Salicornia species distributed in Surala Chilaka and other estuarine regions of the Bahuda estuary in Ganjam district, Odisha were studied. Salicornia brachiata is a potential halophyte for production of Green Salt, Plants popularly known as Glasswort, Sea Asparagus are cooked and eaten as salad or are pickled. It is also a good fodder for Cattle, Sheep and Goat. Plant material is also used as raw material in paper and board factories. Its seeds yield high quality edible oil which is highly Poly Unsaturated and is similar to Safflower Oil in fatty acid. Three study sites were selected in different parts of the Bahuda Estuary for collection of data on hydrographical studies of the estuary and distribution and density of halophytes including Salicornia populations. 4X4M quadrants were used to get the data on density of the Salicornia populations in the estuarine regions. Maximum density (3254 plants/hec.) was reported for the species Salicornia brachiata and minimum density (97 plants/hec.) for the species Prosphis chelensis in the different parts of Bahuda estuarine habitats.

Hexagonal crystalline Magnus' green salt analogues prepared from hydroxy-functionalised Pt and Pd complexes.

New Magnus' green salt (MGS) analogues, [M(dabdOH)2][MCl4]·2H2O (dabdOH = (2S,3S)-2,3-diaminobutane-1,4-diol; M = Pd (1) and M = Pt(2)), in which [M(dabdOH)2]2+ and [MCl4]2- are stacked alternately to form linear chains, were obtained as hexagonal plate crystals. The hexagonal shape and large crystal size are unprecedented features as MGS analogues. An unusual trigonal grade separation of chain complexes has been revealed by the structural analysis. 1 and 2 exhibited remarkable yellow and pink colours, respectively, which are derived from weak M⋯M interactions. The dabdOH ligand, which has an additional hydrogen donor group (hydroxy group), produces a multiple-hydrogen-bond network. The combination of intrachain and interchain hydrogen bonds gives a two-dimensional (2D) hydrogen-bond sheet, and each 2D sheet is indirectly connected by hydrogen bonds via lattice water molecules. The OH-functionalised ligand greatly increases the hydrophilicity of the MGS analogues and yields the largest single crystals of all MGS analogues reported so far. The trigonal grade-separated chain structure is likely due to the geometric matching between the periodicity of chains and the short axis width of the chain. This strategy opens up new insight for preparing large crystals of MGS analogues and for constructing trigonal grade-separated nanowires in molecular crystals.

Dimethyl sulfoxide fosters larger micelles of docusate sodium in the mixed solutions with water

Docusate sodium also referred to as sodium bis(2-ethylhexyl)sulfosuccinate and dioctyl sulfosuccinate sodium (AOT) represents a green salt with proven potential across pharmacy, biology, and medicine. Physicochemical understanding of its inherent structural patterns, transport properties, and phase behavior in solutions is a challenging but essential endeavor. We hereby report conductometry, surface tension, density, and dynamic light scattering measurements of AOT in the dimethyl sulfoxide (DMSO)-water mixtures. The ab initio simulations are used to shed light on the electron density distributions and non-covalent interactions in the systems of our interest. We determine critical micelle concentration (CMC) and thermodynamic parameters of micellization (Gibbs free energy, enthalpy, and entropy) using the conductometry data at 298.15, 303.15, 308.15, 313.15, and 318.15 K. The CMC of AOT increases as DMSO mole fraction in the DMSO-water mixture increases. Negative free energies of micellization are observed over the entire investigated temperature range. Furthermore, higher contents of DMSO foster micellization gradually.The high contents of DMSO (X > 0.3) in the DMSO-water mixtures lead to abrupt changes in CMC and thermodynamics of AOT micellization. We link such changes to the formation of the DMSO self-associates and the associated structural changes in the liquid phase. The dynamic light scattering measurements reveal that larger micellar agglomerates and multilamellar AOT vesicles emerge at high DMSO fractions. The reported data fosters the thoughtful design of practically important systems in medicine.

CONSTRAINTS AND CHALLENGES OF SALT FARMING IN OCCIDENTAL MINDORO, PHILIPPINES

This study drew the profile of the salt farm owners and farmers in Occidental Mindoro, Philippines; their salt production characteristics in terms of salt farm size, material used for salt beds and intended use of the salt produced and post-harvest practices. It also identified the constraints and challenges faced by the salt farm owners and farmers. Key Informant Interview using an interview guide was used to gather data from 52 salt farm owners/farmers. Results of the study indicate that the salt farm owners and farmers are males, between 41-55 years old married and belong to large households. The salt production area is 10 hectares or less, clay (from Vigan) and stones are used to line the crystallizers, and salt produced include agricultural grade salt for the coconut fertilization, yellow quality raw salt for bagoong and dried fish production, cleaning purposes, green quality raw salt for human consumption, iodized salt for human consumption (table salt), washed and refined salt for human consumption (table salt) and food industries (chips, biscuits). Findings of the study also revealed that majority of the salt farmers did not own a warehouse to store their salt and used sacks to package the salt. It is recommended that the Occidental Mindoro Salt Industry Road Map be translated into reality by providing government support to the industry in the form of research and development projects and programs on salt production, post-harvest, logistics and marketing strategies, provision of loan facility to augment capitalization and encourage industry-academe and government line agencies collaboration for an inclusive Occidental Mindoro Salt Industry revitalization.

THE BLUE GREEN PATINA ON SCULPTURES CAST IN COPPER AND ITS ALLOYS - THEIR CHEMISTRY AND AESTHETICS

Copper and its alloys have a tendency to naturally corrode and form a blue green finish over them. This blue green finish has been observed in everyday copper and bronze utensils and even in famous sculptures like statue of liberty. Artists have long taken advantage of this patina to achieve aesthetic of desolateness, age, and damage. This patina tends to change the luster of the metal from reflective to matt and color from pink (gold in case of brass and bronze) to bright blue or green. Artists are known to use this change to add to visual language of their sculptures. The current paper takes in account the whole spectrum of blue – green patinas, from bright blue azurites to dull green verdigris and also dark green copper chloride salts. The paper discusses the chemistry behind the formation of this patina, tests age old recipes and discusses aesthetics with respect to famous Indian sculptors.

Ultra-high response acetone gas sensor based on ZnFe2O4 pleated hollow microspheres prepared by green NaCl template

In this study, ZnFe2O4 pleated hollow microspheres were synthesized by a one-step chemical vapor deposition (CVD) method using NaCl as a green salt template, and successfully used for the detection of acetone gas. NaCl as a green non-polluting and easy-to-remove structural template effectively modulate the morphology and structure of ZnFe2O4. The prepared sensitive materials were observed by SEM and TEM to have dense solid, hollow, pleated hollow and nanosheet structures, respectively. Among them, ZnFe2O4 pleated hollow microspheres exhibited a large specific surface area (185.24 m2/g) and the best sensing performance. Compared with other materials, ZnFe2O4 pleated hollow microspheres presented a response of up to 95.0 for 100 ppm acetone at the optimal working temperature of 200 °C. The large specific surface area and superior surface permeability exhibited by the pleated hollow structure effectively increased the reaction sites and overall utilization of the sensitive material both internally and externally, which resulted in ultra-high response properties to acetone. The ZnFe2O4 pleated hollow microspheres prepared using NaCl green template had excellent acetone molecular sensitivity properties, which is expected to be a promising sensitive material for acetone gas sensors.

A novel low temperature and green salt bath nitriding of titanium alloy

ABSTRACT A novel low temperature and green salt bath nitriding of TC4 titanium alloy was developed by adding a certain amount of K2SO4 in the KNO3 and NaNO3 salt bath. The results show that compared with as-received TC4 alloy, the surface hardness and tribological properties of the nitrided titanium alloy were greatly improved. Furthermore, based on the theoretical and experimental analysis of the effects of the K2SO4 on the inhibition of the cyanide in the nitriding salt bath and tribological properties of the nitrided samples, wonderful discoveries were obtained. The tribological properties of the nitrided samples were dominated by not only the surface hardness but also the subsurface hardness. Moreover, there exists an optimum value for K2SO4 addition (about 1 wt-%): K2SO4 can not only effectively inhibit cyanide production but also cause the hardness in the nitride layer subsurface to further be improved, resulting in the further enhancement of the tribological properties.

Microbial Involvement in Carbon Transformation via CH4 and CO2 in Saline Sedimentary Pool.

Simple SummaryMethane and carbon dioxide are commonly found in the environment and are considered the most important greenhouse gases. Transformation of these gases is in large carried by microorganisms, which occur even in extreme environments. This study presents methane-related biological processes in saline sediments of the Miocene Wieliczka Formation, Poland. Biological activity (carbon dioxide and methane production or methane oxidation), confirmed by stable isotope indices, occurred in all of the studied Wieliczka rocks. CH4-utilizing microbes constituted 0.7–3.6% while methanogens (represented by Methanobacterium) only 0.01–0.5% of taxa present in the Wieliczka Salt Mine rocks. Water activity was the key factor regulating microbial activity in saline subsurface sediments. Generally, CO2 respiration was higher in anaerobic conditions while methanogenic and methanotrophic activities were dependent on the type of rock.Methane and carbon dioxide are one of the most important greenhouse gases and significant components of the carbon cycle. Biogeochemical methane transformation may occur even in the extreme conditions of deep subsurface ecosystems. This study presents methane-related biological processes in saline sediments of the Miocene Wieliczka Formation, Poland. Rock samples (W2, W3, and W4) differed in lithology (clayey salt with veins of fibrous salt and lenses of gypsum and anhydrite; siltstone and sandstone; siltstone with veins of fibrous salt and lenses of anhydrite) and the accompanying salt type (spiza salts or green salt). Microbial communities present in the Miocene strata were studied using activity measurements and high throughput sequencing. Biological activity (i.e., carbon dioxide and methane production or methane oxidation) occurred in all of the studied clayey salt and siltstone samples but mainly under water-saturated conditions. Microcosm studies performed at elevated moisture created more convenient conditions for the activity of both methanogenic and methanotrophic microorganisms than the intact sediments. This points to the fact that water activity is an important factor regulating microbial activity in saline subsurface sediments. Generally, respiration was higher in anaerobic conditions and ranged from 36 ± 2 (W2200%t.w.c) to 48 ± 4 (W3200%t.w.c) nmol CO2 gdw−1 day−1. Methanogenic activity was the highest in siltstone and sandstone (W3, 0.025 ± 0.018 nmol CH4 gdw−1 day−1), while aerobic methanotrophic activity was the highest in siltstone with salt and anhydrite (W4, 220 ± 66 nmol CH4 gdw−1 day−1). The relative abundance of CH4-utilizing microorganisms (Methylomicrobium, Methylomonas, Methylocystis) constituted 0.7–3.6% of all taxa. Methanogens were represented by Methanobacterium (0.01–0.5%). The methane-related microbes were accompanied by a significant number of unclassified microorganisms (3–64%) and those of the Bacillus genus (4.5–91%). The stable isotope composition of the CO2 and CH4 trapped in the sediments suggests that methane oxidation could have influenced δ13CCH4, especially in W3 and W4.

Surface Characterization and Physiochemical Evaluation of P(3HB-co-4HB)-Collagen Peptide Scaffolds with Silver Sulfadiazine as Antimicrobial Agent for Potential Infection-Resistance Biomaterial.

Poly(3-hydroxybutyrate-co-4-hydroxybutyrate) [P(3HB-co-4HB)] is a bacterial derived biopolymer widely known for its unique physical and mechanical properties to be used in biomedical application. In this study, antimicrobial agent silver sulfadiazine (SSD) coat/collagen peptide coat-P(3HB-co-4HB) (SCCC) and SSD blend/collagen peptide coat-P(3HB-co-4HB) scaffolds (SBCC) were fabricated using a green salt leaching technique combined with freeze-drying. This was then followed by the incorporation of collagen peptides at various concentrations (2.5–12.5 wt.%) to P(3HB-co-4HB) using collagen-coating. As a result, two types of P(3HB-co-4HB) scaffolds were fabricated, including SCCC and SBCC scaffolds. The increasing concentrations of collagen peptides from 2.5 wt.% to 12.5 wt.% exhibited a decline in their porosity. The wettability and hydrophilicity increased as the concentration of collagen peptides in the scaffolds increased. In terms of the cytotoxic results, MTS assay demonstrated the L929 fibroblast scaffolds adhered well to the fabricated scaffolds. The 10 wt.% collagen peptides coated SCCC and SBCC scaffolds displayed highest cell proliferation rate. The antimicrobial analysis of the fabricated scaffolds exhibited 100% inhibition towards various pathogenic microorganisms. However, the SCCC scaffold exhibited 100% inhibition between 12 and 24 h, but the SBCC scaffolds with SSD impregnated in the scaffold had controlled release of the antimicrobial agent. Thus, this study will elucidate the surface interface-cell interactions of the SSD-P(3HB-co-4HB)-collagen peptide scaffolds and controlled release of SSD, antimicrobial agent.

From the saltpan to the plate: An evaluation of the use of the edible halophyteSalicornia ramosissimain catering

AbstractThe halophyte speciesSalicornia ramosissimahas long been consumed as food and is currently regarded as a high‐value gourmet item. However, given that these plants grow in estuarine areas, often impacted by pollution, and are prone to the accumulation of ions, the risks associated with food borne pathogens or toxic metals has to be carefully considered. The objective of this work was to gather evidence thatS. ramossissimaharvested locally in an estuarine system (Ria de Aveiro, Portugal) can be safely consumed as a healthy and catering‐amenable food. Fresh shoots, taken as green vegetables, and dried powdered shoots (green salt) intended as seasoning, were analysed for total aerobic bacteria, total coliforms,Escherichia coli,Bacillus cereusand fungi (yeasts and moulds). The nutritional profile and the concentration of macro and micro elements, including potential toxic elements, was also established. Fresh shoots and green salt were incorporated in catering meals (soup and a meat dish) and subjected to sensory analyses. The microbiological quality of fresh shoots and green salt was compliant with the guidelines for salad greens and herbs and spices, respectively. The nutritional and elemental profile revealed that fresh shoots have a high content in fibre and NaCl. From the concentration of Na determined in green salt, a daily dose of 7 g was estimated as corresponding to the recommended daily dietary intake Na. None of the other elements was present in concentrations that could exceed the dietary intake limits. In the sensory tests, fresh shoots were well accepted as salad greens but green salt, used as seasoning, was considered as insufficient in terms of saltiness and does not completely substitute cooking salt. The results confirm the nutritional and sensory value ofS. ramossisimaand represent a promising prospect for the incorporation of locally harvested or crop cultivated plants in catering meals.

Production of Colored Phosphate Coatings on Steel

Phosphating has long been successfully used as a method of protecting metal products and structures from corrosion. The possibility of obtaining non-ferrous phosphate coatings on steel by cold method was investigated. Compositions of cold phosphating solutions for the deposition of colored phosphate coatings of green and blue colors are proposed. To obtain green phosphate films, chromium salts and procyon olive green dye were introduced into the compositions of cold phosphating solutions. To obtain phosphate films of orange color, cobalt salts were introduced into the compositions of cold phosphating solutions. To obtain blue phosphate films, methylene blue and Prussian blue were introduced into the compositions of cold phosphating solutions. It was found that colored phosphate films are worse at preventing metal corrosion. Colored phosphate coatings have a higher porosity and are less uniform compared to modified phosphate films.

Halophytes of the Mediterranean Basin-Underutilized Species with the Potential to Be Nutritious Crops in the Scenario of the Climate Change.

Halophyte plants are adapted to saline environments and represent a novel type of crops given their possible uses at both culinary and industrial levels. In this work, the nutritional quality of different Mediterranean halophyte species, Atriplex halimus, Salicornia fruticosa, and Cakile maritima, was evaluated under conditions of high salinity. For this, plants were grown at different NaCl concentrations (0, 100, 200, and 300 mM) and the contents of proteins, total lipids, polyphenols, and mineral elements were analyzed as well as growth. Of the three species, C. maritima was the most sensitive to salt stress and therefore showed the highest phenolic compounds content. By contrast, whereas salinity increased the amounts of proteins and phenolics with respect to the control in A. halimus and S. fruticosa, it decreased them in C. maritima. Plants of A. halimus accumulated higher amounts of Na+ in their leaves, but the level of this ion, considering human consumption, was below that of other culinary halophyte species. In conclusion, all the results indicate that these three halophyte species grown at high salt levels represent optimal crops for—new foodstuff—production as green salt or spice due to their nutritional potential.

In this issue of Chem, Flood and co-workers demonstrate spatially and electronically isolated cationic dyes in crystalline charge-by-charge ion-pairing systems based on sandwiched [2 + 1]-type anion complexes of a π-electronic cyanostar macrocycle; these dyes exhibit fluorescent colors and intensities similar to those in solution.

Structure, Dynamics, and Photophysical Properties of a Series of [Pt(NH2R)4]-[PtX4] Complexes.

Theoretical investigations of the structural, dynamics, and photophysical properties of Magnus' green salt complex and its derivatives obtained with different substituent were carried out at different levels of theory with a particular focus on the structure and the dynamics of the complex in the ground state and the excited state. The present work illustrates the results of both the quantum mechanics formulation of the time dependent density functional theory (TDDFT) (LR-TDDFT-QM) and TDDFT based Born-Oppenheimer molecular dynamics (LR-TDDFT-BOMD) within the linear response theory. The appropriate choice of the functional within the LR-TDDFT-QM approach appears to be of major importance to get relatively satisfactory results for the photophysical properties and the absorption spectra of such type of complexes. These effects were characterized through the polarization of the basis set function. Regarding our current knowledge of the properties of Magnus' salts, LR-TDDFT-QM and LR-TDDFT-BOMD were performed on a series of complexes of the type [Pt(NH2R)4]-[PtX4], with R denoting an alkyl group and X is a halogen. The effects of the low and medium range Pt-Pt distance upon the absorption wavelength were explored. Available data in the literature of the electronic structure of such material correlated to our results indicate that, the substituent has a double effect both on the shapes and position of the absorption bands. A perceptive shift of the absorption wavelengths is observed, a consequence of the structure and dynamics of the complex in the ground state. The distortion observed in the Pt-Pt distance is found to be a direct consequence of the rotational motion of groups of atoms. By association of the different theoretical approaches, several interesting properties in the ground state and the excited state were determined.

Ultrastructural Characteristics of Slow and fast twitch Muscle Fibers of Rats after a Forced Swimming Cycle against a Background of Introduction of Green Tea Extract and Ammonium Salts

Finding and studying the mechanisms of action of substances of natural origin that would reduce fatigue and restore the performance of skeletal muscles under extreme physical loads are very important tasks of sports physiology and medicine. A comparison of the effects of decaffeinated green tea extract (GTE) and ammonium chloride (AChl), which we previously tested separately and in combination with GTE in the forced swimming model, allowed it to be established that has a greater stimulative effect than does GTE. In the present work, on the basis of electron microscopy data, morphometric studies of m. soleus (SOL) and m. extensor digitorum longus (EDL) muscle fibers of rats were conducted after a forced swimming cycle after the effect of GTE and low doses of ammonium salts (chloride (AChl) or carbonate (ACar)). In GTE group rats, the adaptation to physical load mainly occurs due to an increase in the average area of mitochondria in SOL muscles. In AChl group rats, the adaptation is caused by an increase in the average area of mitochondria in EDL muscles, while, at the same time, the average area of transversely oriented (in relation to the cut plain) T-tubules (TTs) in these muscles decreases along with an increase in the portion of longitudinally oriented TTs, indicating muscle fiber breaks. The combined action of AChl and GTE provides an additive functional effect due to an increase in the average area and volumetric density of mitochondria in EDL muscles and average area of TTs in SOL and EDL muscles, as well as their amount in EDL muscles. In ACar group rats, the functional effect is caused by an increase in the average area of TTs in EDL muscles and their amount in SOL muscles. At the same time, the portion of longitudinal TTs in EDL muscles (and therefore muscle fiber breaks) increases. In the group of combined ACar and GTE effect, changes in mitochondrial apparatus were detected in slow twitch, but especially in fast twitch muscles, as well as an increase in the area of TTs in SOL muscles. Analysis of ultrastructural characteristics indicates that the efficiency of preparations is mainly caused by adaptive changes of TTs and fast twitch muscle mitochondria, but it increases with the involvement of slow twitch muscle fibers in structural and functional adaptation to extreme physical load.

Probing the structural and electronic response of Magnus green salt compounds [Pt(NH2R)4][PtCl4] (R = H, CH3) to pressure.

Despite possessing the desirable crystal packing and short PtPt stacking distances required for a large piezoresistive response, the conductivity-pressure response of the Magnus green salt [Pt(NH3)4][PtCl4] is extremely sluggish. Through a combination of high-pressure X-ray diffraction and hybrid-DFT solid state calculations this study demonstrates that the poor conductivity-pressure response is due to a low volumetric compression anisotropy, a relatively large ambient pressure band gap and a lack of dispersion in the conduction band. Ligand modification (from NH3 to NH2CH3) does not enhance the piezoresistive response, causing even lower anisotropy of the volumetric compression and an unexpected phase transition at above 2 GPa. This study demonstrates that consideration of frontier band dispersion is a key design criterion, alongside crystal packing and PtPt stacking distances, for piezoresistive materials.

Multicomponent Assembled Systems Based on Platinum(II) Terpyridine Complexes

Platinum(II) terpyridine complexes have received tremendous attention in recent years because of their square-planar geometry and fascinating photophysics. Bottom-up self-assembly represents an intriguing approach to construct well-ordered supramolecular architectures with tunable optical and electronic properties. Until now, much effort has been devoted to the fabrication of monocomponent platinum(II) terpyridine-based assemblies. The next step is to develop multicomponent coassembled systems via the combination of platinum(II) terpyridine complexes with other π-organic and -organometallic molecules. The implementation of electron/energy transfer processes renders advanced functionality to the resulting coassemblies. For the fabrication of discrete multicomponent architectures, a feasible protocol is to construct preorganized molecular tweezers and macrocycles with the involvement of platinum(II) terpyridine complexes as the panel units. In view of their planar surface and positively charged character, such supramolecular receptors are capable of encapsulating electron-rich polyaromatic hydrocarbons and organometallic guests via donor-acceptor charge-transfer and/or metal-metal interactions. Intermolecular hydrogen bonds can be further incorporated between the molecular tweezers receptor and the polyaromatic hydrocarbon guests, giving rise to the strengthened binding affinity and sensitive stimuli-responsiveness. On this basis, multilayer donor-acceptor stacks have been obtained via the precise control over the number of pincers, which feature enhanced complexation strength and superior functionality. Moreover, platinum(II) terpyridine-based macrocycles are more suitable for guest accommodation than the corresponding molecular tweezers receptors in light of their definite size and constrained environment. Stimuli-responsive elements can be conveniently implemented into the rigid spacers of the molecular tweezers and macrocyclic receptors, facilitating the capture and release of the sandwiched guests in a highly controlled manner. On the other hand, long-range-ordered supramolecular polymers have been successfully fabricated with linear, hyperbranched, and cross-linked topologies by employing platinum(II) terpyridine-based molecular tweezers/guest recognition motifs as the non-covalent connecting unit. The degree of polymerization of the resulting donor-acceptor-type supramolecular polymers can be efficiently modulated by incorporating intermolecular hydrogen bonds between the molecular tweezers receptor and the complementary guest unit. An alternative approach toward extended multicomponent donor-acceptor assemblies is to mimic the structure of Magnus' green salt. A delicate balance of non-covalent driving forces between homo- and heterocomplexation processes and a deeper understanding of thermodynamic and kinetic behaviors play the decisive roles in the final arrangement of the coassembled structures. Overall, multicomponent coassembly of platinum(II) terpyridine complexes into well-ordered nanostructures would open up a new avenue toward functional supramolecular materials that are especially promising for sensing, optoelectronics, and catalytic applications.
