摘要：

Electrode films of porous aluminum oxide are used as microstructural templates for the immobilization of bilayer assemblies of octadecyltrichlorosilane and N-methyl-N prime -octdecyl-4,4 prime -bipyridinium chloride. Voltammetric and chronocoulometric studies in dilute ferrocyanide solutions reveal ion-exchange binding of ferrocyanide in the head group region of the bilayer assembly. The maximum quantity of the bound ions is reached near the point of complete charge neutralization of the viologen surfactant by ferrocyanide.
