rings by means of Pd-catalyzed cross-coupling reactions, which lead to monomers 1 and 2. Copolymers P1 and P2 obtained by means of anodic polymerization have been characterized by spectroscopic and electrochemical methods. Electrochromism was observed for both polymers. The experimental data supported by density functional theory modeling explain the influence of alkyl chain substitution on the properties
在初步的DFT计算的基础上,设计了基于2,7-取代的an吨结构单元的p型半导体聚合物,该结构体显示出很高的平面度。2,7-双(
