摘要
研究了一种新合成的杂环席夫碱Ｎ，Ｎ＇－二乙酰吡啶缩双苯胺在铂电极上的电化学聚合、聚合膜与钴（Ⅱ）的配合反应及聚合物膜的电化学性质。实验结果表明，该席夫碱可在电极表面通过电化学聚合反应形成具有良好的机械、化学和电化学稳定性的聚合物膜，该聚合物膜可与钴离子形成稳定的配合物，这种配合物对生物分子一氧化氮的电化学氧化有显著的催化作用。
A new heterocyclic Schiff base, N, N' 2,6 diacetylpyridine bis(aniline), was synthesized. The electrochemical polymerization of the Schiff base , the reactivity of the polymer towards cobalt(Ⅱ) ion and electrochemical characteristics of the metallated polymer were investigated. It was found that the Schiff base was electropolymerized at the platinum electrode by cyclic voltammetric method or constant potential method. The experimental results also showed that the nitrogen atoms in the polymer retained the coordinating ability and could react with cobalt(Ⅱ) ion to form a metallated polymer which showed strong catalytic effects on the electrochemical oxidation of nitric oxide.
