This article summarizes recent progress in the post-functionalization of conjugated polymers by electrochemical methods. These electrochemical polymer reactions typically proceed via electrochemical doping of a conjugated polymer film, followed by chemical transformation. Examples include the quantitative oxidative fluorination of polyfluorenes and oxidative halogenation of polythiophenes, as well as the reductive hydrogenation of polyfluorenones. The degree of functionalization, otherwise known as the reaction ratio, can be controlled by varying the charge passed through the polymer, allowing the optoelectronic properties of the conjugated polymers to be tailored. Wireless bipolar electrodes with an in-plane potential distribution are also useful with regard to the electrochemical doping and reaction of conjugated polymers and allow the synthesis of films exhibiting composition gradients. Such bipolar electrochemistry can induce multiple reaction sites during electrochemical polymer reactions.
本文总结了通过电化学方法对共轭聚合物进行功能化后的最新进展。这些电化学聚合反应通常通过电化学掺杂共轭聚合物薄膜，然后进行化学转化来进行。例如，定量的电化学氧化氟化聚芴和电化学氧化卤化聚噻吩，以及聚芴酮的还原氢化。功能化程度，也称为反应比，可以通过改变通过聚合物的电荷来控制，从而可以调整共轭聚合物的光电性能。具有平面内电位分布的无线双极电极对于共轭聚合物的电化学掺杂和反应也很有用，并允许合成具有组成梯度的薄膜。这种双极电化学可以在电化学聚合反应过程中诱导多个反应位点。
