  通过二硫代氨基甲酸酯路线合成3,4-二苯基取代的聚亚苯基亚乙烯基，低带隙聚合物

  摘要：

  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。
