Applications of photoinduced electron transfer and hydrogen abstraction reactions to chemical and electrochemical conversion processes. Part I. Progress report, March 1, 1981-July 1, 1983
Goal is to study light-driven electron transfer and hydrogen atom abstraction processes with emphasis on reactions giving rise to net chemical or electrochemical conversion. The original proposal focused on studies using substrates excitable with visible light - ranging from metal complexes, porphyrins and metalloporphyrins to dyes and ketones - and quencher-mediators capable of acting as electron donors or acceptors by virtue of having multiple closely spaced redox levels. During the past eighteen months results were obtained in five areas: generation and reaction of reducing and oxidizing radicals and radical ions in photoelectrochemical cells; studies of Weitz-type quenchers having stable one-electron redox products; two-electron oxidative and reductive quenching processes with Weitz-type systems in solution and organized media; photoredox reactions of indigo dyes; and modification of photochemical reactivity by formation of amylose inclusion complexes in aqueous and partially aqueous solutions.
