导电聚合物的电化学性质

Electrochemical Properties of Conducting Polymers

综述了几种有代表性的导电聚合物———聚吡咯、聚苯胺、聚噻吩等的电化学特性及其电化学掺杂/脱掺杂反应的机理,介绍了聚对苯撑乙烯(PPV)等光电活性共轭聚合物的循环伏安特性及其HOMO和LUMO能级的电化学表征方法;还对导电聚合物的电化学稳定性以及取代基对共轭聚合物电子结构的影响进行了讨论.

Electrochemical properties of several representative conducting polymers, including polypyrrole, polyaniline and polythiophene etc., were reviewed. The electrochemical doping/dedoping mechanism of the conducting polymers was discussed. The cyclic voltammetric behavior and the electrochemical characterization of the HOMO and LUMO energy levels of the optoelectronic-active conjugated polymers (poly(p-phenylene vinylene) (PPV) derivatives, etc.) were described. The electrochemical stability of the conducting polymers and the effect of substituents on the electronic structure of the conjugated polymers were also discussed.
