Photosynthesis at the Microscale

Abstract

Several novel ligands and complexes (including mononuclear, binuclear, and trinuclear) were synthesized and characterized. All ligands and complexes were characterized by elemental analysis, UV-visible, 1H NMR, and EPR spectroscopy, and cyclic voltammetry, where appropriate. Photocatalytic studies were carried out in acidified acetonitrile. Initial studies were also carried out with water oxidation catalysts (WOCs) in order to generate O2 and H+ ions in aqueous media. Hydrogen was not generated on photolysis of a novel mixed-metal ruthenium(ll)-cobalt(ll) complex, Ru(bpy)2(tbtp)Co(dmgBF2)2(H20)](PF6)2*5H20 in acidic acetonitrile solution; while oxygen was produced in water on photolysis in the presence of a WOC, Na6[Bi2Co4(H20)2W16058]*65H20, and [Ru(bpy)3]CI2. Electrosynthetic studies involving Co(ll) and Ni(ll) complexes proved that H2 was produced on several electrodes in aqueous media.
