摘要

在三氟化硼乙醚(BFEE)溶液中N甲基吲哚可以阳极氧化聚合生成聚(N-甲基吲哚).单体在BFEE中的起始氧化电位为0.95V

远低于单体在CH3CN+0.1mol/L Bu4NBF4体系中的起始氧化电位(1.23V).BFEE中获得的聚(N-甲基吲哚)膜具有良好的电化学性质和荧光性质.红外光谱表明聚合反应发生在2

3位.

Abstract

Poly(N—methylindole)films were synthesized electrochemically by direct anodie oxidation of N—methylindole in pure boron trifluoride diethyl etherate(BFEE)．The oxidation potential of N—methylindole in this medium was measured to be only 0.95 V versus SCE

which was lower than that determined in acetonitrile+0.1 mol／L Bu4NBF4(1．23 V)．Poly(N—methylindole)films obtained from this medium showed good electrochemical behavior and good chemical stability．Poly(N—methylindole)films in dedoped state is soluble in common strong polar organic solvents such as CH2Cl2

dimethyl sulfoxide(DMSO)

N—dimethylformamide(DMF)．Its structure has been examined by infrared and UV—spectra．Structural analysis confirmed that the polymerization of N-methylindole ring occurred at the 2

3 positions．Fluorescent spectral studies indicated that the emission spectrum had a peak at 380 nm.
