| Part I. The electrochemical anodization of an iron or cobalt electrode placed in contact with the coordination bridging ligand bisbipyridylalkane results in the formation of a polymer film, or "metal macrocluster with bridging ligands", on the surface of the electrode. Preliminary information is presented on the properties of the polymer films generated. Properties include corrosion inhibition characteristics in the case of iron, and for cobalt, a means of immobilizing the cobalt bipyridine moiety. Additionally, the polymer structure and formation of 4-methyl-4{dollar}spprime{dollar}vinyl-2,2{dollar}spprime{dollar}-bipyridine-containing complexes is presented. Results from TLC and Fourier Transform Mass Spectroscopy demonstrate that the structure is a vinyl-backbone with trisbipyridine appendages as opposed to the "metal macrocluster with bridging ligands".; Part II. The functioning of the multivalent redox system, tris(5,5{dollar}spprime{dollar}-dicarbo(3-acrylyl-1-propoxy)-2,2{dollar}spprime{dollar}-bipyridine ruthenium(II) as both a redox and an ohmic conductor incited further study of the conduction mechanism of such systems. A general equation is derived which accounts for both diffusive and (electric) field-assisted electron hopping through a matrix comprising any number of simple or polyvalent redox couples (a polyvalent redox couple has three or more valence states with one-electron interconversions). The development of equations necessary to perform a computer simulation of the electronic flux, and "independent" species quasi-flux for these immobilized multivalent redox systems is also presented. |
