摘要
合成了含有不同烷基链取代的N-丙烯酰氧癸基咔唑(MACZ10)和N-丙烯酰氧十二烷基咔唑(MACZ12),通过自由基聚合得到聚N-丙烯酰氧烷基咔唑(PMACZ).分子量分析表明,随着烷基链长度的增加,聚合物分子量减小,分布变宽.荧光光谱表明,随着烷基链长度的增加,聚合物在353nm处的发射峰逐渐减弱.在四氢呋喃和体积分数为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-丙烯酰氧烷基咔唑)(PPMACZ)薄膜.PPMACZ薄膜具有良好的氧化还原活性、热稳定性和蓝色发光性能,聚合物氧化还原可逆性随着烷基链长的增加而增加,且发射峰变宽.
Two novel acrylate functionalized monomers N-[10-(acryloxy) decyl]carbazole(MACZ10) and N-[12-(acryloxy) dodecyl]carbazole(MACZ12),which incorporate a carbazole moiety at the terminal of the hydrocarbon chain,were designed and synthesized.Through radical polymerization of MACZs led to the formation of two precursor polymers,poly(N-[10-(acryloxy) decyl]carbazole)(PMACZ10) and poly{ N-[12-(acryloxy) dodecyl]carbazole}(PMACZ12).The results of GPC indicate that molecular weight of polymer decreased with the growth of alkyl chain,fluorescence spectral show that the emission peak at 353 nm of the polymer decreased with the growth of alkyl chain.Free-standing and conducting conjugated polycarbazole network poly-{ poly(N-[10-(acryloxy) decyl]carbazole) }(PPMACZ10) and poly-{ poly(N-[12-(acryloxy) dodecyl]carbazole) }(PPMACZ12) films were synthesized electrochemically by direct anodic oxidation of PMACZ10 and PMACZ12 in THF containing additional 10%(volume fraction) boron trifluoride diethyl etherate(BFEE).PPMACZs films obtained from this medium show good electrochemical behavior and good thermal stability.As-formed PPMACZs films were characterized by UV-Vis,infrared,fluorescence spectroscopy and thermal analysis.Fluorescence spectral studies revealed that PPMACZs films were good blue light emitters.
