以二苯醚（DPE）为原料，在含5%浓硫酸（SA）的三氟化硼乙醚（BFEE）溶液中，采用直接阳极氧化法制备了电导率为4.4 × 10 - 1 Scm-1的高质量聚二苯醚（PDPE）膜。在饱和甘汞电极（SCE）上，DPE在纯BFEE中的起始氧化电位仅为1.37V，远低于在乙腈+0.1molL-1四氟硼酸四丁基铵溶液中的起始氧化电位（1.98Vvs.SCE）.在BFEE +5%SA的混合电解液中，SA的加入使单体的氧化电位下降到1.18V（SCE）。从该介质中获得的PDPE膜显示出良好的氧化还原活性和稳定性，即使在浓SA中。Dedoped PDPE薄膜部分溶于强极性有机溶剂二甲基亚砜。荧光光谱研究表明，可溶性PDPE是一个很好的蓝光发射体，量子产率为0.30。红外光谱和量子化学与C4.
High-quality poly(diphenyl ether) (PDPE) films with electrical conductivity of 4.4 X 10 -1 S cm -1 were synthesized electrochemically by direct anodic oxidation of diphenyl ether (DPE) in boron trifluoride diethyl etherate (BFEE) containing 5% concentrated sulfuric acid (SA) (by volume). The oxidation potential onset of DPE in pure BFEE was measured to be only 1.37 V versus a saturated calomel electrode (SCE), which was much lower than that determined in acetonitrile +0.1 mol L -1 tetrabutylammonium tetrafluoroborate (1.98 V vs. SCE). The addition of SA to BFEE can further decrease the oxidation potential onset of the monomer to 1.18 V versus SCE in the mixed electrolyte of BFEE + 5% SA. PDPE films obtained from this medium showed good redox activity and stability even in concentrated SA. Dedoped PDPE films were partly soluble in the strong polar organic solvent dimethyl sulfoxide. Fluorescent spectral studies indicated that soluble PDPE was a good blue-light emitter with a quantum yield of 0.30. Infrared spectroscopy and quantum chemistry and C 4 .
