摘要: 采用电化学聚合方法在水溶液中制备出Fe(CN)_6~(4-)嵌入的聚吡咯膜修饰电极, 电极具有稳定的Fe(CN)_6~(4-)/Fe(CN)_6~(3-)电化学响应, 其氧化、还原电位与电解质溶液中H~+浓度有关。借助XPS、IR和ESR方法对聚合物膜结构进行表征, 探讨嵌入物种Fe(CN)_6~(n-)和聚吡咯之间的相互作用, 提出一种可能的轨道相互作用模式。

Abstract: A procedure is described whereby Fe(CN)_6~(n-) (n=3 or 4)-incorporated polypyr- role (PP) film can be formed on electrodes by electrochemical polymerization in aqueous solutions. Stable electrochemistry of the electrode thus formed is observed. The redox potential is affected by changes of the concentration of H~+ in the elec- trolyte. By means of XPS, IR and ESR characterizations, the interactions between the incorporated species Fe(CN)_6~(n-) and PP~+ has been investigated. A possible model of the orbital interactions involved in the film has been discussed.
