使用薄层电池研究了聚噻吩衍生物（PT）的电化学卤化，例如聚（3-己基噻吩）（PHT）、聚（噻吩-alt-9,9-二辛基芴）（PTF）和聚（联噻吩-alt-9,9-二辛基芴）（PBT）。与使用传统的烧杯型电池相比，使用薄层电池显着提高了聚噻吩衍生物电化学卤化的反应活性和电流效率。此外，薄层电池的使用减少了所需电解液的量。此外，噻吩环上氯原子的完全取代使所得聚合物的光学和电化学性能发生了显着变化。
The electrochemical halogenation of polythiophene derivatives (PTs) such as poly(3-hexylthiophene) (PHT), poly(thiophene-alt-9,9-dioctylfluorene) (PTF) and poly(bithiophene-alt-9,9-dioctylfluorene) (PBT) was investigated using a thin-layered cell. The reactivity and the current efficiency of the electrochemical halogenation of polythiophene derivatives were markedly improved by using the thin-layered cell as compared to using a conventional beaker-type cell. Moreover, the use of the thin-layered cell reduces the amount of electrolytic solution required. In addition, the optical and electrochemical properties of the obtained polymers were significantly changed by the complete substitution of chlorine atoms onto the thiophene ring.
