indicated that π-conjugations of the polymers were expanded; in particular, those of polymers containing the long alkoxy side chains were developed effectively. All the polymers showed electron-donating properties in cyclic voltammometry measurements and formed soluble charge-transfer complexes with 7,7,8,8-tetracyano-p-quinodimethane (TCNQ). After the complexation with TCNQ, the conductivities of the polymers
供电子性与dithiafulvene部分(π共轭聚合物4)或用diselenafulvene部分(5)由来自芳族二炔(派生chalcogenoketenes的环加成聚合制备的3)。聚合物的溶解度很大程度上取决于结构。二
硒烯富烯聚合物(5)的溶解度低于相应的二
硫富烯聚合物(4)。长烷基链的连接增强了在非极性溶剂中的溶解度。聚合物的结构通过IR和1确证。1 H NMR谱。紫外可见测量表明,聚合物的π共轭得到了扩展。特别是,有效地开发了具有长烷氧基侧链的聚合物的那些。所有聚合物在循环伏安法测量中均显示出供电子性,并与7,7,8,8-四
氰基-对-喹二
甲烷(TCNQ)形成可溶性电荷转移络合物。与TCNQ络合后,聚合物的电导率增加。
