Contributions of Multimethod Personality Assessment in Indirect Evaluation

Indirect assessment is a useful tool in forensic evaluation, especially in cases of threat assessment. To this end, we illustrated the ability to conceptualize a complicated case (i.e., Theodore John Kaczynski) using an indirect approach, with a particular emphasis upon dimensional frameworks of personality. Raters who were unrelated to Mr. Kaczynski’s case and with expertise in relevant domains were asked to study information available in the public domain about Mr. Kaczynski and provide ratings using several assessment instruments. Our aim was not to provide a professional clinical opinion, but rather engage in scholarly discourse about the utility of instruments. Mr. Kaczynski was rated to demonstrate characteristics associated with lone actor terrorists. He showed an elevation on a measure of psychosis, and raters conceptualized trauma as an important aspect of his functioning. He demonstrated impairments in detachment and psychoticism (Criterion B of the AMPD) and interpersonal functioning (Criterion A of the AMPD). Clinical conceptualizations for Mr. Kaczynski emphasized schizotypal and paranoid personality disorders. This analysis of an infamous case about which considerable data are publicly available demonstrates the ease with which indirect and multimethod assessment can be applied and integrated in forensic assessment, using modern conceptualizations of personality pathology.

A Critical Discourse Analysis of The Use of Modal Verbs in Former Prime Minister Speech During Covid-19

This article is an effort at looking at critical discourse analysis strategies and modality use in a speech text by Tan Sri Dato’ Muhyiddin Yassin, the eighth Prime Minister of Malaysia. This research hopes to explain how discourse is part of a social process, and to show that the social process can be explained with a systematic and critical discourse analysis approach. A nation leader’s speech can be meaningful and highlight his actions to the public. In the Malaysian context, a leader’s speech transcript is usually used as a main reference to better understand how the discourse is used by leaders to influence or deliver their ideologies to the people. This research will study the use of modality to identify or highlight the speaker’s intentions that is contained within the discourse. Modality helps in identifying discourse functions and illustrates how power is hidden within discourse. In this case, the critical discourse analysis theoretical framework is used to explore complex social issues in a leader’s discourse in order to examine power relationships and how it is applied within the economical, sociological and political context. The critical discourse analysis introduced by Norman Fairclough (1995) will be applied in this research. The analysis will follow the three dimensional framework which is the text, discourse practice, and sociocultural practice analyses. This research will use the Covid 19 Special Address by YAB Tan Sri Dato Muhyiddin Yassin, Prime Minister of Malaysia, as data in examining a nation leader’s discourse practices. Findings showed that the new government utilizes the power of language or discourse by using modality in delivering messages, fulfilling intentions, and gathering support to reinforce political power.

Social Workers' Choice Making in Supporting Nature Activities by Parents and Children in Shelters.

Visiting a natural environment such as a garden or park helps people to recover from stressful circumstances. Women’s shelters and homeless shelters have started to integrate nature in their work, especially for families who seek temporary refuge, with the aim to support parents’ functioning and resilience. For professionals who want to facilitate engagement with nature among their clients, it may be helpful to learn how other professionals choose nature activities for the support of parents. The current study was aimed to uncover how social workers choose a nature activity for the support of parents, resulting in a model that can be used as a reflective tool among shelter professionals. The model is based on an analysis of actions of professionals, captured in case descriptions written by shelter professionals about parenting supportive nature activities that they facilitated for families under their care. The model shows that social workers promoted a back-and-forth between children’s exploration away from the parent and being with the parent. In facilitating these interactions, social workers used nature as an environment with stress reducing and strengthening capacities for parents and as an environment with supportive qualities for children’s play. A dimensional framework was extracted that described how professionals may choose activities.

Perceived value in a UNESCO World Heritage Site: the case of Quito, Ecuador

PurposeThe city of Quito is a World Heritage Site (WHS) in Ecuador and the city owns one of the best-preserved and extensive historic centers in Latin America for cultural tourism. This study aims to identify the factors that constitute perceived value construct at the WHS of Quito.Design/methodology/approachThis research collects data from tourists who have visited the city of Quito, Ecuador. A total of 381 on-site questionnaires are used. Data have been analyzed using exploratory factorial analysis.FindingsResults regarding the dimensional structural framework of perceived value indicate that perceived value at the WHS of Quito has five factors: (1) monetary and non-monetary costs (MNC), (2) staff service quality (SSQ), (3) tourist offer accessibility (TOA), (4) destination attractiveness (DA) and (5) information accessibility (IA).Originality/valueTwo new factors of accessibility have been proposed in this study for measuring consumer value at a WHS. Perceived value and accessibility have been treated as two separate subjects in academic literature before. However, this article contributes to the understanding of perceived value at WHS, including factors linked to accessibility. Both managerial and theoretical implications for WHS are discussed.

Lewis Acid Catalyzed Synthesis of Vinylene Linked Two Dimensional Covalent Organic Frameworks

Comprehensive SummaryVinylene linked covalent organic frameworks (COFs) have drawn extensive attention due to their desirable stability, carbon conjugation and opto‐electronic properties. Suitable catalyst is a key factor in the synthesis of vinylene linked COFs, and proton acids and bases are widely reported as catalysts so far. Herein, we report the synthesis of vinylene linked COFs using Lewis acid ZnCl2 as catalyst for the first time. Four COFs with hexagonal pores of different sizes are synthesized by the reaction of 2,4,6‐trimethyl triazine and a series of aromatic aldehydes.

Two–dimensional metal organic nanosheet as promising electrocatalysts for carbon dioxide reduction: A computational study

Designing high–selectivity and low-cost electrocatalysts are highly desirable for the carbon dioxide reduction reaction (CO2RR). Herein, the promising CO2RR electrocatalysts were screened out from several two–dimensional metal organic frameworks (2D–MOFs) nanosheets by means of density functional theory (DFT) calculations. According to the computational results, we identified three promising CO2RR catalysts for different products. The main products of CO2RR by Fe3(HHTP)2, Co3(HHTP)2 and Ir3(HHTP)2 are HCOOH, CH3OH and CH4, respectively. Particularly, the Ir3(HHTP)2 shows remarkable high catalytic activity with lowest limiting potential (UL = –0.22 V) for CH4 production. Therefore, the rational controlled chemical modifications of 2D–MOFs materials provide a new scenario for the design of promising novel CO2RR electrocatalyst.

Zirconium Metal-Organic Cages: Synthesis and Applications.

ConspectusFor the last two decades, materials scientists have contributed to a growing library of porous crystalline materials. These synthetic materials are typically extended networks, including metal-organic frameworks (MOFs) and covalent organic frameworks (COFs), or discrete materials like metal-organic cages (MOCs) and porous organic cages (POCs). Advanced porous materials have shown promise for various applications due to their modular nature and structural tunability. MOCs have recently garnered attention because of their molecularity that bestows them with many unique possibilities (e.g., solution-processability, structural diversity, and postsynthetic processability).MOCs are discrete molecular assemblies of organic ligands coordinated with either metal cations or metal oxide clusters of different nuclearities, resulting in architectures with inherent porosity. Notably, the molecular nature of MOCs endows them with easy solution-processability unattainable with traditional framework materials. To date, a number of stable MOCs have been reported, such as those based on Rh (Rh-O bond energy: 405 ± 42 kJ/mol), Fe (Fe-O bond energy: 407.0 ± 1.0 kJ/mol), Cr (Cr-O bond energy: 461 ± 8.7 kJ/mol), Ti (Ti-O bond energy: 666.5 ± 5.6 kJ/mol), and Zr (Zr-O bond energy: 766.1 ± 10.6 kJ/mol). Paddle-wheel MOCs have also shown great stability in aqueous environments due to their rigid backbones. The zirconium MOC (Zr-MOCs) family emerges as a class of very robust cages for which their high bond energy endows them with high hydrothermal stability.In 2013, we reported the first four zirconocene tetrahedrons assembled from trinuclear zirconium oxide clusters with ditopic or tritopic organic ligands. Since then, significant progress in the rational design of Zr-MOC has led to an assortment of structures dedicated to meaningful applications.In this Account, we highlight the recent progress in synthesizing Zr-MOCs and Zr-MOC-based higher dimensional frameworks and their applications dedicated in our laboratories and beyond. The general Zr-MOC synthetic strategy involves assembling Zr trinuclear clusters with organic ligands (rigid or flexible) containing various functional groups. This chemistry has afforded cages with structural versatility and active sites, e.g., amino groups, for postsynthetic modifications (PSMs). Since the extrinsic porosity of cage-based frameworks is relatively weak, the resulting frameworks are susceptible to structural rearrangement after solvent removal. To circumvent this limitation, increasing the hydrogen bond ratio and strength between interlinked cages and conducting in situ catalytic polymerizations have been reported to afford permanently porous structures amenable to host-guest reactions.To expand their potential applications, multifunctional Zr-MOCs are highly desired. Such multivariate MOCs can be attained by either employing the isoreticular expansion strategy to create MOCs with high surface areas or using mixed-ligand approaches to afford heterogeneous MOCs. In addition, amorphous MOCs, flexible organic ligands, new functionalities, and MOC-based extended networks are exciting new approaches to developing materials with structural versatility and enhanced characteristics. Thereby, we believe the stability and versatility of the Zr-MOC family hold great potential in expanding and addressing challenging applications.

3,5-Dibromosalicylaldehyde nicotinoylhydrazone and 4,4′-bipyridine appended new Zn(II) Coordination Polymer: Secnidazole sensing and Rhodamine B photocatalytic degradation properties

Coordination polymers (CPs) are assorted class of multidimensional materials that could be deployed as sensors and photocatalysts against the photodegradation of aromatic dyes existing in the waste-water discharge. Herein, a new Zn(II)-based coordination polymer (CP) [Zn(dsn)(4,4’-bipy)0.5] (1) has been synthesized by reacting Schiff base ligand 3,5-dibromosalicylaldehyde nicotinoylhydrazone (dsn) and 4,4′-bipyridine (4,4’-bipy) with Zn(NO3)2·6H2O and characterized using elemental analysis, FTIR, TGA, powder X-ray diffraction and single crystal X-ray diffraction techniques. The single crystal X-ray diffraction studies revealed tetragonal pyramidal geometry around Zn(II) and the architecture of 1 is stabilized by π···π interactions operating between pyridine ring of dsn and 4,4’-bipy. Also, other weak non-conventional weak interactions provide stability and engender supramolecular three dimensional framework in 1. The CP has been used as fluorescent sensor to detect antibiotics and exhibits selective sensing of secnidazole (SIZ) with limit of detection (LOD) 8.59 × 10−7 M. This showcase of 1 can act as an efficient and selective sensor for SIZ even in presence of other antibiotics. Also, the CP has been used as photocatalyst for photodegradation of Rhodamine B (Rh B) and degrades 80% of Rh B in 100 min. The plausible mechanism employing which CP 1 executed sensing of secnidazole (SIZ) and photocatalysis of Rh B have been explained with aid of theoretical calculations.

Tailoring delicate pore environment of 2D Covalent organic frameworks for selective palladium recovery

Palladium is a rare resource, and its content in the earth’s crust is very low. Thus, its selective recovery from a secondary source is of great importance but a challenging task. Herein, we have constructed a series of bipyridine-based two dimensional (2D) covalent organic frameworks (COFs) TFBBPY-COF, TFBBPY-OH-COF and TFBBPY-OMe-COF, and explored their extraction performance towards palladium in aqueous solutions. It is found that by tailoring the pore environment of these COFs, TFBBPY-OMe-COF shows a highly efficient adsorption and excellent selectivity for palladium recovery, and the maximum sorption capacity is up to 532 mg g−1, which is the highest value among the crystalline porous adsorbents reported up to now. Furthermore, TFBBPY-OMe-COF has been successfully employed to capture Pd(II) with a high selectivity (92.3%) in a simulated solution derived from a waste printed circuit boards. Spectral experiments and theoretical calculations reveal that the excellent adsorption of palladium is mainly attributed to the multiple hydrogen bonds of C–H---Cl and coordination of O and pyridine-N to Pd(II).

Ostinatos in Black-Atlantic traditions: generic-specific similarity and proximity

Ostinatos of sub-Saharan Africa, South America, and the Caribbean are continually repeated rhythms also known as “timelines.” Taking as a starting point the ostinato termed the “Standard Pattern,” generic and specific features of Black-Atlantic ostinatos are analyzed: in European-derived theory, these features correspond to the quantity and quality of musical intervals. Like the standard pattern, other ostinatos that have been employed in several Black-Atlantic traditions and comprise a rhythmic structure that corresponds to the structure of hyperdiatonic scales in contemporary European-derived pitch theory; other widespread ostinatos considered have a complementary, hyperpentatonic structure. Interpreted in terms of Gestalt grouping principles, both of these kinds of ostinatos maximize similarity and proximity. Other ostinatos of these traditions can be construed as variants of hyperdiatonic or hyperpentatonic ostinatos. Differences of similarity and proximity that these variants manifest are analyzed in terms of adjacent swaps, fusions and fissions, and moduli that encompass two or more ostinatos’ least common multiples. In turn, similarity and proximity measures for rhythmic ostinatos are shown to parsimoniously clarify aspects of pitch relations, including the general notion of evenness, within 1- dimensional frameworks for pitch and time.

Theoretical Insights on the Two-Dimensional Transitional Metal Trihydroxytriaminophenalenyl for Highly Efficient Carbon Dioxide Electroreduction

Nowadays, to relieve the environmental issues and the energy depletion, one of the most practicable and feasible technologies is the electrochemical reduction of CO2 to high value added chemicals. In this aspect, the bottleneck is to develop novel catalysts with high efficiency and selectivity. Based on this idea, in this work, a series of two dimensional transitional metal doped trihydroxytriaminophenalenyl, i.e., M3(THTAP)2, have been studied as the catalysts for CO2 reduction reaction (CO2RR). Our study showed that these catalysts are stable and have metallic character, which is conducive to electroreduction reaction. Products CH4, CH3OH and HCOOH are obtained for the studied catalysts. Cr3(THTAP)2 is the best catalyst for producing CH4. Ir3(THTAP)2 produces CH3OH as the final product and the overpotential is 0.34 V. Both Pt3(THTAP)2 and Pd3(THTAP)2 are good CO2RR catalysts to produce HCOOH with the small overpotentials of 0.17 and 0.23 V, respectively. Thus, these two dimensional transition metal organic frameworks exhibit great potential as the electrochemical catalysts for high performance CO2 electro-catalytic process. We anticipate that this work may shed new light on the development of high performance metal organic framework based electrocatalysts.

Two new 3D lanthanide-organic frameworks based on rod-shaped metal-carboxylate chain SBU: Synthesis, characterization and luminescent detection of Fe3+ and S2− in aqueous solution

The study of metal-organic frameworks (MOFs) as luminescence sensors for the detection of polluting molecules and ions are of great importance to the health of all creatures in the world. In this research field, lanthanide ions, especially for Eu3+ and Tb3+, have intrinsic advantages based on their outstanding luminescent properties. To develop smart luminescence sensors towards heavy metal ions and acid anions, two new lanthanide(III)-based MOFs: {[Ln2(btpdc)3·DMF·2H2O]·2DMF·4H2O}n (Ln ​= ​Eu (1), Tb (2), H2btpdc ​= ​benzo[b]thiophene-2,6-dicarboxylic acid) were designed and synthesized under solvothermal condition based on a dicarboxylate ligand H2btpdc. Single crystal X-ray diffraction tests show the two complexes are isostructural with three dimensional (3D) porous framework structure. Notably, both of them exhibit good chemical stability in water. Under the excitation of ultra-violet light, 1 can exhibit strong Eu3+-based red light emission in both solid state and aqueous suspension while 2 doesn't show observable luminescence emission. The luminescence sensing experiments performed on 1 reveal that it can be employed as a smart “turn-off” luminescence sensor for the detection of Fe3+ or S2− in aqueous solution with high selectivity, low detection limit, good anti-interference ability and recyclability. The obtained quenching constant Ksv and detection limits are 2.316 ​× ​104 ​M−1 and 0.26 ​μM, respectively, for Fe3+, and 1.38 ​× ​104 ​M−1 and 1.05 ​μM, respectively, for S2−.

Researching epistemic beliefs in history education: A review

Departing from the pioneering work of VanSledright and Maggioni (2016), this article revisits questions about epistemic beliefs and the role these beliefs play in the teaching and learning of history. Eighteen recent studies on epistemic beliefs of history teachers (n=7) and students (n=11) are reviewed, guided by questions regarding conceptualization, relationships with other constructs (e.g., historical reasoning and teaching beliefs), expression of beliefs in teachers and students, differences in age and educational level, suggestions for pedagogical principles, and contextual factors that inhibit or support history teachers in “putting their beliefs into practice”. Results reveal that epistemic beliefs are conceptualized based on developmental and dimensional frameworks, although most recent studies integrated developmental and dimensional approaches. Important findings regarding students and teachers are highlighted, resulting in implications for research and practice.

Pesticide detection with covalent-organic-framework nanofilms at terahertz band

Development of rapid molecular detection technologies is critical for the safer and smarter urban agriculture, medicine, and pro-environment. The emergent terahertz (THz) spectroscopy has its distinct advantages of being non-destructive, label-free and able to trace intermolecular and intramolecular vibrations, yet it suffers from the low performance of sensing materials available and their high fabrication cost. Here, we introduce a reticular material -- two dimensional (2D) covalent organic frameworks (COFs) and prepare their nanofilms as the lossy layer for THz absorbers. The COF film can be directly deposited on the dielectric layer of THz absorbers via an in-situ wet-chemistry growth. It possesses designable hierarchical structures, high specific areas of 736–971 m2/g, and precise nanopores of 1.6–2.1 nm, depending on its 2D COF constituents. The resulting THz absorber has been tested for pesticide detection. It presents a limit of detection at 2.2 ng and a selective response of 2.7–7.8 times that of interferents such as saccharides, antibiotics, and dyes, satisfying the need for practical application. Such flexible filmy sensor can measure the pesticide residue on the surface of apple for practical application. The THz sensor also demonstrates high stability over 1000 cycles of bending. Use of reticular nanofilm as the responsive layer may permit the future development of high-performance THz absorbers and other sensors for rapid molecular recognition.

Work-leisure blending: An integrative conceptual review and framework to guide future research.

Since the industrial revolution, work and leisure have largely been considered opposing domains. A growing number of organizations, however, enable and/or promote blending leisure activities into the workplace. Similarly, several conceptualizations across different disciplines examine how work and leisure can coexist. These different conceptualizations have yielded a rich but fragmented theoretical account of work-leisure blending. To address this problem, we provide a comprehensive theoretical integration of multiple literature streams where research has explored work-leisure blending. Further, we develop a tripartite dimensional framework designed to elucidate the central dimensions of work-leisure blending (i.e., segmentation-integration, unstructured-structured, and independent-interactive) undergirding this phenomenon. Using this framework as a theoretical foundation, we then discuss important contextual considerations and future research directions related to work-leisure blending.

Synthesis, characterization, and luminescent temperature sensing of two resorcin[4]arene-based Zn(II) coordination polymers

The assemblies of two octacarboxylate-functionalized resorcin[4]arene and Zn2+ cations produce two coordination polymers, namely, [(CH3)2NH2][Zn4(L1)(μ3-OH)(H2O)]·DMF (1) and [(CH3)2NH2]2[NaZn3(L2)(μ2-OH)(H2O)]·2H2O (2). 1 and 2 show two dimensional (2D) frameworks. Remarkably, 1 and 2 produce intensive blue emissions and long lifetimes owing to d10 metals of Zn and resorcin[4]arene based ligands. More importantly, the intensity-based luminescence reveals that 1 and 2 are extremely more linear with temperature, indicating that they can be applied for potential temperature sensors.

Characterizing the ASD-ADHD phenotype: measurement structure and invariance in a clinical sample.

Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD) have considerable overlap, supporting the need for a dimensional framework that examines neurodevelopmental domains which cross traditional diagnostic boundaries. In the following study, we use factor analysis to deconstruct the ASD-ADHD phenotype into its underlying phenotypic domains and test for measurement invariance across adaptive functioning, age, gender and ASD/ADHD clinical diagnoses. Participants included children and youth (aged 3-20 years) with a clinical diagnosis of ASD (n = 727) or ADHD (n = 770) for a total of 1,497 participants. Parents of these children completed the Social Communication Questionnaire (SCQ), a measure of autism symptoms, and the Strengths and Weaknesses of ADHD and Normal Behaviour (SWAN) questionnaire, a measure of ADHD symptoms. An exploratory factor analysis (EFA) was performed on combined SCQ and SWAN items. This was followed by a confirmatory factor analysis (CFA) and tests of measurement invariance. EFA revealed a four-factor solution (inattention, hyperactivity/impulsivity, social-communication, and restricted, repetitive, behaviours and interests (RRBI)) and a CFA confirmed good model fit. This solution also showed good model fit across subgroups of interest. Our study shows that a combined ASD-ADHD phenotype is characterized by two latent ASD domains (social communication and RRBIs) and two latent ADHD domains (inattention and hyperactivity/impulsivity). We established measurement invariance of the derived measurement model across adaptive functioning, age, gender and ASD/ADHD diagnoses.

Synthesis of various dimensional metal organic frameworks (MOFs) and their hybrid composites for emerging applications – A review

Metal organic frameworks (MOFs) represent the organic and inorganic hybrid porous materials. MOFs are low dense and highly porous materials which in turn provide large surface area that can accumulate and store numerous molecules within the pores. The pore size may also act as a mesh to separate molecules. The porous nature of MOFs is beneficial for altering the intrinsic properties of the materials. Over the past decade, different types of hybrid MOFs have been reported in combination with polymers, carbon materials, metal nanoparticles, metal oxides, and biomolecules for various applications. MOFs have also been used in the fabrication of electronic devices, sensors, energy storage, gas separation, supercapacitors, drug delivery and environmental clean-up. In this review, the unique structural orientation, exceptional properties and recent applications of MOFs have been discussed in the first section along with their porosity, stability and other influencing factors. In addition, various methods and techniques involved in the synthesis and designing of MOFs such as solvothermal, electrochemical, mechanochemical, ultrasonication and microwave methods are highlighted. In order to understand the scientific feasibility of MOFs in developing new products, various strategies have been applied to obtain different dimensional MOFs (0D, 1D, 2D and 3D) and their composite materials are also been conferred. Finally, the future prospects of MOFs, remaining challenges, research gaps and possible solutions that need to be addressed by advanced experimental design, computational models, simulation techniques and theoretical concepts have been deliberated.

Structure modulation, selective dye adsorption and catalytic CO2 transformation of four pillared-layer metal-organic frameworks

In this paper, a series of metal-organic frameworks (MOFs), namely, [Co(pip)(4,4′-bpy)]n (1), [Co2(pip)2(bibp)]n (2), [Mn(pip)bidmp]n (3) and [Ni(pip)(bibp)(H2O)]n (4) (bpy ​= ​4,4′-bipyridine, bibp ​= ​4,4-bis(imidazolyl)biphenyl, bidmb ​= ​1,4-bis(1-imidazoly)-2,5-dimethylbenzene), have been solvothermally synthesized based on the main ligand 6-(3-pyridyl)isophthalic acid (H2pip) and structurally characterized by various methods. These MOFs all present three dimensional (3D) pillared-layer frameworks, and through systematic modulation of auxiliary ligands and metal ions, their structures can be well regulated from nonporous to porous. Considering their excellent thermal and water stability, the dye removal properties from water solutions of these MOFs were further studied, and notably, 2 which has the largest porosity of the four MOFs, exhibits very fast selective adsorption of methyl orange over Rhodamine B (MO/RhB) with a total MO uptake amount of 83.4 ​mg ​g−1. Moreover, the catalytic CO2 transformation properties of these MOFs were also carried out under mild conditions, of which 2 exhibited the highest catalytic activity with 69.57% yield for propylene carbonate and 50.55% for butylene carbonate, respectively.

Three dimensional fluorene-based polyamides facile to transfer ion designed for near-infrared electrochromic application and detection for explosive

Near-infrared electrochromic (NIR EC) functional materials are attracting increasing attention owing to their great potential for applications in smart window. However, obtaining high performance NIR EC material with high optical transmittance contrast, fast redox switching and long-term cyclic stability is still a challenge. Introducing four triphenylamine (TPA) units into one planar fluorene core to build robust three dimensional (3D) framework which not only makes ion and electron move freely but also provides sufficient space and storage sites for hosting ions will meet the requirement. Here, three kinds of new polyamides (PAs) based on conjugated fluorene as the bridge unit were designed and polycondensized by a new diamine N, N'-(9,9-bis(4-(diphenylamino)phenyl)-9H-fluorene-2,7-diyl)-bis(N-(4-methoxyphenyl) benzene-1,4-diamine), with three kinds of dicarboxylic acids to form TPAF-6F, TPAF-CA and TPAF-OA. The obtained new PAs exhibit impressive solution-processability and excellent thermal stability. Cyclic voltammograms (CV) and differential pulse voltammograms (DPV) of the PAs imply strong electronic coupling within molecule. Furthermore, the TPAF-OA film exhibits excellent EC performance with multi-coloured EC behaviour, high optical contrast (92%), high coloration efficiency (203 cm2 C−1) and outstanding cycle stability (optical contrast remains 90% over 1400 cycles) in the NIR range. TPAF-CA also shows impressive fluorescence (PL) quantum efficiency which could be used as sensor for explosive and nonvolatile flash memory properties. The strategy of introducing 3D framework block into polymer will pave a way for fabricating high performance optoelectronic devices.
