It has been demonstrated that the dithiocarbamate precursor route is a suitable pathway towards poly(thienylene vinylene) (PTV)-type low-band-gap polymers. Two particular dithiocarbamate precursor polymers and the corresponding conjugated polymers, poly(3,4-diphenyl-2,5-thienylene vinylene) and poly(3,4-bis(4-butylphenyl)-2,5-thienylene vinylene), have been studied. The introduction of butyl side chains
已经证明,二硫代氨基甲酸酯前体途径是通向聚(亚噻吩乙烯撑)(PTV)型低带隙聚合物的合适途径。两种特殊的二硫代氨基甲酸酯前体聚合物和相应的共轭聚合物,即聚(3,4-二苯基-2,5-噻吩亚乙烯基)和聚(3,4-双(4-丁基苯基)-2,5-噻吩亚乙烯基)。研究过。丁基侧链在后者中的引入导致其在普通有机溶剂中的优异溶解性。两种聚合物均以直接的方式和良好的产率制备。用原位FT-IR和UV-vis光谱研究了前体聚合物向共轭结构的热转化。同样,利用后一种技术,确定了带隙,并研究了热致变色效应,并将其与未取代的PTV进行了比较。
