聚(N-十二烷基-3-苯基吡咯)的研究

Synthesis and Characterization of Poly(N-lauryl-3-phenyl-pyrrole)

合成了一种吡咯的双取代衍生物：Ｎ－十二烷基－３－苯基吡咯，并用化学氧化法对其实施了聚合反应。该反应生成的导电聚合物可溶于一般有机溶剂，用溶剂蒸发制膜的方法可制得柔软的自支撑薄膜，用四电极方法测得掺杂态薄膜的电导率约为０．０５Ｓ／ｃｍ。并通过元素分析、ＧＰＣ、ＦＴ－ＩＲ、１Ｈ－ＮＭＲ等手段对其分子结构进行了表征。

This paper described the synthesis of a new monomer:N-lauryl-3-phenyl pyrrole. It can polymerize by oxidative coupling method with ferric chloride to give a soluble conductive polymer. The conductivity of its solution-cast film is about 5×10 -2 S/cm by four-probe method. The IR and NMR spectra of the polymer are consistent with the regular 2,5-bondings of pyrrole rings, so the polymer has a well-defined structure. The element analysis verified that the doping level is low, so the polymer is much lower in conductivity than polypyrrole.
