synthesis of two potentially electropolymerizable electron donor–acceptor dyes characterized by a cruciform 4,4′-spirobi[cyclopenta[2,1-b:3,4-b′]dithiophene] core is here outlined. The new molecules feature two perpendicularly aligned cyclopentadithiophene branches, each one having an electrodimerizable, electron donor triphenylamine unit and an electron acceptor dicyanovinylene group. By merging these structural
两种潜在的可电聚合电子供体-受体染料的设计与合成,其特征为十字形的4,4'-spirobi [cyclopenta [2,1- b:3,4- b此处概述了'] [dithiophene]核心。新分子具有两个垂直排列的环戊二噻吩分支,每个分支具有一个可电二聚的电子给体三苯胺单元和一个电子受体二氰基亚乙烯基。通过合并这些结构元素,共轭环戊二噻吩发色团的光吸收能力扩展到可见光谱的宽广区域。通过电化学沉积技术从一种染料获得的光电活性膜保留了产生光致电荷分离态和传输空穴的能力,使该材料成为供体-受体聚合物的独特实例,在有机光电器件的开发中具有潜在的应用前景。
