Electrochemical polymerization of 3,4-ethylenedioxythiophene in the presence of water-soluble fullerene derivatives was investigated. The electronic structure, morphology, spectroelectrochemical, electrochemical properties and near-IR photoconductivity of composite films of poly(3,4-ethylenedioxythiophene) with fullerenes were studied for the first time. It was shown that fullerene with hydroxyl groups creates favorable conditions for the formation of PEDOT chains and more effectively compensates for the positive charges on the PEDOT chains. The near-IR photoconductivity results from the generation of charge carriers due to electron transfer from the photoexcited PEDOT molecule to the fullerene acceptor.
研究了在水溶性富勒烯衍生物存在下3,4-乙撑二氧噻吩的电化学聚合。首次研究了聚（3,4-乙撑二氧噻吩）与富勒烯复合膜的电子结构、形态、光谱电化学、电化学性质和近红外光电导性。结果表明，带有羟基的富勒烯为聚3,4-乙撑二氧噻吩（PEDOT）链的形成创造了有利条件，并能更有效地补偿PEDOT链上的正电荷。近红外光电导性源于光激发的PEDOT分子向富勒烯受体的电子转移所产生的电荷载流子。
