Abstract

We have designed a molecular system consisting of a heteroleptic [Ru(bpy)(2)L](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.
