摘　　要：By oxidative coupling polymerization a novel electroactive polyamide,with fixed conjugated length of oligoaniline(amine-capped aniline pentamer)in the main chain,was successfully synthesized.The structure of the electroactive polyamide was confirmed via FTIR and NMR.The UV-Vis spectra were used to monitor the chemical oxidation process of the reduced polyamide.Moreove,its electrochemical behavior was investigated by cyclic voltammetry(CV)measurement.It was found that the obtained electroactive polyamide with amine-capped aniline pentamer segments had a quasi-reversible electrochemical property in the cyclic voltammetry,which was the same as polyaniline.Its electrical conductivity is about 1.24×10-6 S/cm at room temperature upon preliminarily protonic-doped experiment.By oxidative coupling polymerization a novel electroactive polyamide, with fixed conjugated length of oligoaniline （amine-capped aniline pentamer ） in the main chain, was successfully synthesized.

Moreove, its electrochemical behavior was investigated by cyclic voltammetry（CV） measurement. It was found that the obtained electroactive polyamide with amine-capped aniline pentamer segments had a quasi-reversible electrochemical property in the cyclic voltammetry, which was the same as polyaniline. Its electrical conductivity is about 1.24 × 10^-6 S/cm at room temperature upon preliminarily protonic-doped experiment.
