Syntheses of two series of new styryl dyes incorporating thiacrown ether moieties (CSDs 3a−e, 4a−e) are described. 1H NMR and UV−vis measurements show that these compounds exhibit a strong preference for formation of complexes with heavy metal ions. Polarographic measurements allow conversion of relative complex formation stabilityconstants, determined spectrophotometrically, into absolute values

In the paper we present synthesis and characterization of new donor–acceptor thiophene derivatives (TDs) containing vinylbenzo[d]thiazole, vinylpyridine and 1H-imidazo[4,5-f][1,10]phenanthroline residues. Using CELIV method, electron and hole mobility have been studied in the polymer layers based on poly [9,9-bis(6-diethoxyl-phosphorylhexyl)fluorine] (PF-EP) doped with the TDs. Polymer light-emitting
在本文中,我们介绍了含有乙烯基苯并[d]噻唑,乙烯基吡啶和1H-咪唑并[4,5- f ] [1,10]菲咯啉残基的新型供体-受体噻吩衍生物(TDs)的合成和表征。使用CELIV方法,已经研究了掺杂TDs的基于聚[9,9-双(6-二乙氧基-磷酰基己基)氟](PF-EP)的聚合物层中的电子和空穴迁移率。与不含TD的PF-EP相比,包含新合成的聚芴(PF)作为发射层和PF-EP / TD复合材料作为电子传输层的聚合物发光二极管(PLED)在15V时显示出更高的亮度。

The easily available 3-chloropropeniminium salts have recently attained synthetic importance as versatile synthons. As 1,3-bifunctional electrophilic systems, they react easily with different nucleophilic reagents to form numerous acylic and, in particular, heterocyclic compounds. 1.

The electrophilicsubstitution of 6-methylpyrrolo[2,1-b]thiazole has been studied quantitatively. Acetylation, formylation, trifluoroacetylation, and nitrosation occur exclusively at position 5. Further reaction gives 5,7-disubstitution products. Tritylation gives mainly 5,7-ditrityl- and 5-trityl- together with some 7-trityl-6-methyl-pyrrolo[2,1-b]thiazole.
已经对6-甲基吡咯并[2,1- b ]噻唑的亲电取代进行了定量研究。乙酰化,甲酰化,三氟乙酰化和亚硝化仅在位置5发生。进一步的反应产生5,7-二取代产物。三酰化作用主要产生5,7-二苯甲基-和5-三苯甲基-以及一些7-三苯甲基-6-甲基-吡咯并[2,1- b ]噻唑。
