在三氟化硼乙醚（BFEE）中加入80%乙醚（伊卡），通过直接阳极氧化法制备了高质量的聚吲哚-5-羧酸（PICA）膜。从该介质中获得的PICA膜表现出良好的电化学行为和良好的热稳定性，电导率为10 - 2Scm-1。在电化学生长过程中，PICA的掺杂水平增加。Dedoped PICA膜可溶于二甲基亚砜（DMSO）。用紫外-可见光谱、红外光谱和核磁共振氢谱对聚合物的结构进行了表征，结果表明聚合反应发生在C（2）和C（3）位。荧光光谱研究表明PICA是一种良好的蓝光发射体。
High quality poly(indole-5-carboxylic acid) (PICA) films were synthesized electrochemically by direct anodic oxidation of indole-5-carboxylic acid (ICA) in boron trifluoride diethyl etherate (BFEE) containing additional 80% diethyl ether (EE) (by volume). PICA films obtained from this medium showed good electrochemical behavior and good thermal stability with a conductivity of 10−2Scm−1. The doping level of PICA increased during electrochemical growth processes. Dedoped PICA films were soluble in dimethyl sulfoxide (DMSO). The structure of the polymer were studied by UV–vis spectroscopy, FT-IR spectroscopy and1H NMR spectroscopy, which indicated that the polymerization occurred at C(2)and C(3)position. Fluorescent spectral studies indicated that PICA was a good blue-light emitter.
