Photochemical activation and reactivity of polynuclear transition metal complex molecules. Progress report, June, 1980-May 31, 1981

Progress on this project during the past year has proceeded in three different but complementary directions. The first involves a continuing effort to synthesize new and unusual polynuclear transition metal complexes that (1) exhibit multi-electron transfer reactions, (2) can be expected to have long-lived excited states, and/or (3) will undergo photochemically initiated intramolecular energy transfer to produce reactive species. The second involves the electrochemical investigation of multi-electron transfer reactions of polynuclear transition metal complexes. The third is concerned with the study of the photophysics of binuclear complexes in which electron transfer could take place between a photochemically excited metal ion and the metal ion in the same molecule thereby producing two new reactive sites.
