摘　　要：在三氟化硼乙醚(BFEE)中,9,9-二乙基芴(DEF)直接阳极氧化聚合可以获得高质量聚(9,9-二乙基芴)膜(PDEF,电导率2×10-2S.cm-1).DEF在BFEE中的起始氧化电位为1.20 VvsSCE,远低于单体在0.1 mol.L-1Bu4NBF4的CH3CN溶液中的起始氧化电位(1.70 V).在BFEE中获得的PDEF膜具有良好的电化学性质.红外光谱和1H NMR结果表明聚合反应主要发生在2,7位.High quality poly（9, 9-diethylfluorene） （PDEF） films with electrical conductivity of 2 × 10^-2 S · cm^-1 were synthesized electrochemically by direct anodic oxidation of 9, 9-diethylfluorene （DEF） in boron trifluoride diethyl etherate （ BFEE）. The oxidation potential of 9, 9-diethylfluorene in BFEE was measured to be only 1.20 V vs SCE. This value was much lower than that determined in acetonitrile containing 0.1 mol·L^-1 Bu4NBF4（1. 70 V）. PDEF films obtained from BFEE showed good electro- chemical behavior. IR and ^1H NMR spectra indicated that the polymerization mainly occurred at 2-and 7-positions of fluorene.
