摘　　要：以吡咯和二缩三乙二醇为原料合成了N取代吡咯衍生物单体——双-[2-吡咯(乙氧基)]乙烷,并用循环扫描伏安技术研究了该单体的电化学聚合过程。结果表明:在乙腈/高氯酸锂溶液中,双-[2-吡咯(乙氧基)]乙烷在铟锡氧化物导电玻璃(ITO)、Pt、Au、玻璃碳、石墨电极上均能顺利发生反应,形成一定厚度的聚合物膜。但聚合速率、膜的结构、膜的颜色有差异。溶剂水对聚合有明显影响。形成的聚合膜具有良好的电化学稳定性。A new N-substituted derivative monomer of pyrrole-bisF2-（pyrrole） ethoxy]ethane was synthesized by pyrrole and triethylene glycol. Cyclic voltammetry was used to study the process of electropolymerization. The results exhibited that bisF2-（pyrrole） ethoxy]ethane was easy to polymerize on indium tin oxide-coated glass electrode, Pt, Au, glass-carbon and graphite electrodes in acetonitrile using lithium perchlorate as the supporting electrolyte. However, the polymeric speeds, structure and color were different under various experimental conditions. Water solution has obvi- ous influnce on polymerization. The electrochemical stability of this conductive polymer is pretty good.
