Spatial electrochromism in metallopolymeric films of ruthenium polypyridyl complexes
- Univ. of North Carolina, Chapel Hill, NC (United States); and others
Electropolymerized thin films of of poly[Ru(vbpy){sub 2}(py){sub 2}]{sup 2+} (vbpy is 4-vinyl-4{prime}-methyl-2,2{prime}-methyl-2,2{prime}-bipyridine; py is pyridine) were prepared. Photolysis of the films in the presence of chloride ion leads to photochemical substitution of Cl{sup -} for pyridine ligands, the structures of which were confirmed by small spot XPS. The absorption spectra and redox potentials of the ruthenium complexes were altered upon substitution of chloride for the pyridine ligands, suggesting the potential for using these materials to fabricate electrochromic film assemblies on optically transparent electrodes. The spectroelectrochemical response of the films was measured. 47 refs., 14 figs., 4 tabs.
