Synthesis and crystal structures of transition metal ion complexes of di(2-thienyl)imide

Di(2-thienyl)imide, 1, has been shown to chemically polymerize, and, if metal complexes of 1 could be synthesized, the polymer could have potential applications as an ion sensor and environmental remediation agent. As a first step towards this goal, di(2-thienyl)imide is shown to form complexes with Mn (II), Co (II), and Zn (II) perchlorates. The complexes of Mn2+ and Co2+ are isostructural with two di(2-thienyl)imide ligands in equatorial positions and two perchlorate ions axial. The Zn2+ complex has two water molecules in the axial positions and the thiophene rings in the two equatorial ligands are tilted in the same direction from the median plane due to intra- and intermolecular contacts. The crystal structures and infrared spectra, as well as an improved synthesis and polymerization of di(2-thienyl)imide, are reported and discussed.

Transforming the behavior of conventional chromophores from aggregation-caused quenching to aggregation-induced emission

Conventional chromophores tend to have their fluorescence quenched in aggregate states,which was the notorious aggregation-caused quenching(ACQ)effect.The ACQ effect seriously limited the practical applications of conventional chromophores.In contrast to ACQ,agroup of luminescent materials are weakly emissive or even non-emissive in solutions but highly emissive by aggregate formation.This phenomenon was termed"aggregation-induced emission"(AIE).The swiftly development of AIE materials provided a new strategy,which can elimination the ACQ effect by introducing AIE moieties to the ACQ chromophores.The converted ACQ chromophores may have new properties and can be used in new field.This review was aimed to summarize recent progress on the conversion of ACQ chromophores,such as the conversion of triphenylamine derivatives,fused cyclic compounds and rylene diimides derivatives by introducing siloles,substituted ethenes(including tetraphenylethylene,triphenylethylene and triphe-nylethylene carbazole)or triphenylacrylonitrile moieties to them.In addition,the properties and applications of the new materials are introduced briefly.The development trends of this field are also prospected.

Synthesis and characterization of new poly(amide imide)s by direct polycondensation of diamine containing diimide group and diacids using thionyl chloride

A diimide diamine (DIDA) monomer containing both an isopropylidene and arylether group was prepared by reducing the dinitro compound obtained from condensation of 4-nitrophthalic anhydride and 2,2-bis[4-(4-aminophenoxy)phenyl]propane. A series of novel poly(amide imide)s were prepared from DIDA and various diacids by direct polycondensation reaction using an equimolar amount of thionyl chloride in N-methyl-2-pyrrolidone (NMP) at room temperature. Inherent viscosities of these polymers were in the range of 22–70 mL g–1 (Mw = 28 500–120 500 by GPC, Mw/Mn = 1.55–1.80). Most of these polymers are soluble in aprotic polar solvents such as NMP and dimethylsulfoxide and even in less polar solvents, i.e. m-cresol and nitrobenzene. The films had tensile strengths in the range of 103–118 MPa. The glass transition temperatures were observed in the range of 190–285°C. The polymers were stable up to 395°C in nitrogen atmosphere, which revealed good thermal stability compared with a commercial poly(amide imide). Ein Diimid-Diamin-Monomeres (DIDA) mit sowohl einer Isopropyliden- als auch einer Arylether-Gruppe wurde durch Reduktion der entsprechenden Dinitroverbindung hergestellt, die durch Kondensation von 4-Nitrophthalsaureanhydrid und 2,2-Bis[4-(4-aminophenoxy)phenyl]propan erhalten worden war. Aus DIDA und verschiedenen Dicarbonsauren wurde durch direkte Polykondensation mit einer aquimolaren Menge Thionylchlorid in N-Methyl-2-pyrrolidon (NMP) bei Raumtemperatur eine Reihe neuer Polyamidimide erhalten. Die inharenten Viskositaten dieser Polymeren betragen 22–70 mL g–1 (Mw = 28 500–120 500, mittels GPC bestimmt, Mw/Mn = 1.55–1.80). Die Mehrzahl dieser Polymeren ist in aprotischen polaren Losungsmitteln wie NMP und Dimethylsulfoxid und sogar in weniger polaren Losungsmitteln wie m-Cresol und Nitrobenzol loslich. Die Zugfestigkeit von Filmen aus diesen Polymeren liegt im Bereich von 103–118 MPa. Die Glasubergangstemperaturen betragen 190–285°C. Die Polymeren sind unter Stickstoff bis 395°C thermisch stabil, im Vergleich zu einem handelsublichen Polyamidimid ein gur Wert.

親電子的水素添加試薬としてのジイミド

エルカ酸,ステアロール酸混合物のジイミド還元生成物の組成を,ガスクロマトグラフィーによって測定し,前者が速度定数比2.7で後者よりすみやかに水素添加されることを認めた。このように直鎖化合物において,ジイミドが三重結合より二重結合に対して反応性が大きいことは,不飽和結合に対し親電子的に付加することを示す。この付加機構は置換アゾベンゼンのジイミド還元における速度定数比より求めた置換基効果(ハメットのρ値:-0.95)によって確認された。ケイ皮酸置換体でジイミド還元において置換基効果が示されないのは, 二重結合のα 位のカルボキシル基の影響が大きいためと推定される。
