摘　　要：在三氟化硼乙醚(BFEE)中,9,9-二辛基芴可以直接阳极氧化制备高质量聚(9,9-二辛基芴)膜,其电导率为1×10-2S/cm.9,9-二辛基芴在BFEE中的起始氧化电位为1.25Vvs.SCE,低于单体在0.1mol/LBu4NBF4的乙腈溶液体系中的起始氧化电位(1.52Vvs.SCE).BFEE中获得的聚(9,9-二辛基芴)膜具有良好的电化学性质.聚合物部分溶于氯仿、四氢呋喃、二甲基亚砜等极性溶剂.FTIR和1HNMR表明聚合反应主要发生在2,7位.荧光光谱表明聚合物是一种良好的蓝色荧光物质.High quality poly（9,9-dioctylfluorene） films were synthesized electrochemically by direct oxidation of 9,9-dioctylfluorene in pure boron trifluoride diethyl etherate on stainless steel sheet, with polymer conductivity of 1 ×10^-2 S/cm. The initiate oxidation onset of 9,9-dioctylfluorene in such medium was only 1.25 V vs. SCE, which was much lower than that determined in 0.1 mol/L Bu4NBF4 acetonitrile solution （1.52 V vs. SCE）. Polymer obtained from this medium showed good electrochemical behavior and can be partly dissolved in chloroform, tetrahydrofuran, dimethylsulfoxide, etc. FTIR and ^1H NMR spectral investi- gations indicated that the polymerization of monomer occurred mainly at 2,7 positions, and fluorescent spectral studies indicated that the polymer was a blue-light emitter.
