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 LBu4NBF4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.Poly （N-methylindole） films were synthesized electrochemically by direct anodic 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 Ba4NBF4 （ 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, 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.
