聚丙烯酸修饰咔唑的电化学聚合及表征

Electrosynthesis and Characterization of Free-standing Polyacrylate Functionalized Polycarbazole Network Films

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1.34×10-5S·cm-1.1HNMR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.
