| 摘 要： | 在三氟化硼乙醚-硫酸混合电解质溶液中,二苯并呋喃直接阳极氧化聚合可以获得高质量聚(二苯并呋喃)膜.二苯并呋喃在纯三氟化硼乙醚中的起始氧化电位为1.30 VvsSCE,远低于单体在0.1 mol.L-1Bu4NBF4乙腈溶液中的起始氧化电位(2.14 V).硫酸的加入进一步降低了二苯并呋喃的氧化电位.在三氟化硼乙醚-硫酸混合电解质溶液中,二苯并呋喃的起始氧化电位可降低至1.0 V;同时在该体系中获得的聚(二苯并呋喃)膜具有良好的电化学性质和荧光性质. |

| Abstract: | High quality poly(dibenzofuran) films were synthesized electrochemically by direct anodic oxidation of dibenzofuran in mixed electrolytes of boron trifluoride diethyl etherate(BFEE) and sulfuric acid.The oxidation potential of dibenzofuran in pure BFEE was measured to be only 1.30 V vs SCE.This value was much lower than that determined in 0.1 mol·L~(-1)Bu_(4)NBF_(4)acetonitrile solution(2.14 V).The addition of H_2SO_4 to BFEE can further decrease the oxidation potential of the monomer.The oxidation potential of dibenzofuran in the mixed electrolyte of BFEE containing 12.5 % H_2SO_4(by volume) was found to be as low as 1.0 V.Poly(dibenzofuran) films obtained from this medium showed good electrochemical behavior.Fluorescent spectral studies indicated that soluble poly(dibenzofuran) might be a good material for a blue lightemitting device. |
