合成了侧链带有咔唑的N-丙烯酰氧己基咔唑(MACZ), 通过自由基聚合得到聚N-丙烯酰氧己基咔唑(PMACZ), 在四氢呋喃含10%三氟化硼乙醚与四氟化硼四丁基胺的混合电解质溶液中, 直接阳极氧化PMACZ获得自支撑交联网状的聚(聚N-丙烯酰氧己基咔唑)(PPMACZ)薄膜. PPMACZ薄膜具有良好的氧化还原性和热稳定性, 电导率为1.34× 10－5 S•cm－1. 1H NMR和红外光谱表明PMACZ二次聚合反应发生在咔唑单元的3, 6位上, 荧光光谱表明PPMACZ薄膜是一种良好的蓝色发光材料.

A novel acrylate functionalized with pendant carbazole monomer, N-[6-(acryloxy)hexyl]-carbazole (MACZ), was synthesized. The radical polymerization of MACZ led to the formation of a precursor polymer, poly(N-[6-(acryloxy)hexyl]carbazole) (PMACZ). Free-standing and conducting conjugated polycarbazole network poly-{poly(N-[6-(acryloxy)hexyl]carbazole)} (PPMACZ) films were synthesized electrochemically by direct anodic oxidation of PMACZ, which showed good electrochemical behavior and good thermal stability with conductivity of 1.34×10－5 S•cm－1, and were characterized by UV-Vis, infrared, fluorescence spectroscopy and thermal analysis. Fluorescence spectral studies revealed that the PPMACZ films were good blue light emitters.

Key words: polycarbazole, conducting polymer, polyacrylate, electrochemical polymerization, network film
