Akstract. In artificial photosynthesis the chief research goal is to duplicate the function of the photosynthetic unit in nature hut not its structural subunits. In this paper, light-induced electron-transfer processes of Ru-polypyridines as energy-storing systems, in the presence of suitable acceptors and catalysts, are described. New highly photostable photosensitizers are presented. A new approach using supramolecular (non-covalently) connected assemblies in addition to covalently linked systems for energy-storing processes is demonstrated. The use of classical and new Ru-complex assemblies in oxygen or hydrogen generation from water is dealt with. The efficiency of the new systems in the reduction of CO2 to methane is presented.
