在不同电解质和溶剂介质中，在碳纤维微电极上电化学合成了咔唑。通过电化学方法（即，循环伏安法测量、固态电导率测量（四点探针）、分光光度法（紫外/可见光谱（UV-vis）、离位光谱电化学、傅立叶变换红外反射光谱（FTIR-ATR））和扫描电子显微镜（SEM）。就产率、电导率和电荷而言，电接枝的最佳电解质和溶剂是乙腈中的高氯酸钠，其电导率为3.60 mS cm-1，产率为89%，电荷为5.50 C。讨论了扫描速率、投料比、支持电解质和溶剂种类对聚合的影响。
Carbazole was electrochemically synthesized on carbon fiber microelectrodes (CFMEs) in different electrolyte and solvent media. The characterization of polycarbazole thin films formed on micron sized carbon fiber electrodes was performed by electrochemical methods (i.e., cyclic voltammetric measurements, solid state conductivity measurements (four point probe), spectrophotometric methods (ultraviolet/visible spectroscopy (UV–vis),ex situspectroelectrochemistry, fourier transform infrared reflectance spectroscopy (FTIR-ATR)) and scanning electron microscopy (SEM). The best electrolyte and solvent in regards to yield, conductivity and charge for the electro-grafting was sodium perchlorate in acetonitrile, whose conductivity was 3.60 mS cm−1, had a yield of 89% and had a charge of 5.50C. The effects of scan rate, feed ratio, supporting electrolyte and solvent type on the electropolymerization are discussed.
