Production of hydrogen fuel from electrolysis of water would be a practical strategy if scientists could find a “super catalyst” for the water oxidation reaction. A significant challenge in the sustainable hydrogen economy is to design a water oxidation catalyst. Biological water splitting occurs at the oxygen-evolving complex (OEC) of photosystem II (PSII), {Fe} and clusters in {Fe-Fe}, {Fe-Ni} Hydrogenazes and new photosensitizers in DSSC having high efficiency for water photolysis and cheaper than existing. The Electrochemical Solar Cells consists of three components: titanium oxide (or WO3, CuI etc) semiconductor, light-absorbing pigment (the best pigments are rarely metal ruthenium complexes with bipyridyl derivatives as ligands) and electrolyte (Fig. 1). Using the experience and early obtained results in coordination chemistry in LCBA of IC ASM it was elaborated concrete and specific routes for synthesis the: Photosensitizers – the different derivatives of Ferrocene-Porphyrins, 1,1'-ferrocene polypyrrole derivatives; complexes of Ru with 2,6-bis(quinolin-2- yl)pyridine ligands; Cu (II) complex with 3,3´,6,6´-tetracarboxy-2,2´bipyridinic acid; Ni(II) complexes with 2,2′-thiocarbonylbis(N(methoxyphenyl)hydrazinecarbothhioamide); OEC - mixed valence manganese (II,III; III,IV) carboxy-clusters of [Mn3CaO4]and [Mn4CaO4] cubane type. All of they were characterized by modern physical methods.
