Outline of Final Research Achievements

Visible light irradiation of a Ge-porphyrin (1a)/TiO2/ITO anode in photochemical cell induced the generation of short-circuit currents in the presence of aliphatic alcohols as an electron donor. The oxidation of alcohols with the Ge-oxyl complex formed by photoinduced electron transfer from 1a to TiO2 could be a critical process for the production of electricity.
