Abstract

We have designed a molecular system consisting of a heteroleptic [Ru(bpy)₂L]²⁺ chromophore covalently linked to a Mn ^III-Salen unit. We demonstrate the light induced oxidation of the Mn^III center in this putative photo-catalyst assembly to a Mn ^IV high spin intermediate. Both oxidation states have been characterized by transient absorption and EPR techniques.
