以三氯甲烷为溶剂，FeCl 3为氧化剂/试剂，合成了一种新型的可加工导电聚合物聚[3-（4-辛基苯基）噻吩]。该聚合物，这是可溶于有机溶剂，如氯仿，其特征在于使用光学，电学和电化学方法。与聚（3-烷基噻吩）的情况相比，由于聚（噻吩）主链和柔性烷基侧链之间的苯环的分离效应，在该聚合物中观察到抑制的热致变色和热去掺杂。在低掺杂水平下，极化子被发现是电荷载流子
A new, processible conducting polymer, poly[3-(4-octylphenyl)thiophene] has been chemically synthesized in chloroform using FeCl 3 as the oxidant/reagent. The polymer, which is soluble in organic solvents such as chloroform, has been characterized using optical, electrical, and electrochemical methods. A suppressed thermochromism and thermal undoping were observed in this polymer compared to the case of poly(3-alkylthiophene) due to the separation effect of the benzene rings between the poly(thiophene) main chain and the flexible alkyl side chains. At low doping levels, polarons are found to be the charge carriers
