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.
