Copolymers of (Ru(vbpy){sub 3}(PF{sub 6}){sub 2}) and (Os(vbpy){sub 3}(PF{sub 6}){sub 2}) (vbpy = 4-vinyl-4{prime}-methyl-2,2{prime}-bipyridine) have been prepared in solution and by electropolymerization. The ruthenium and osmium monomers were incorporated in the copolymers in different ratios depending on the polymerization method. These results point to fundamental differences between solution polymerization and electropolymerization. In addition, luminescence experiments at liquid-nitrogen temperature and room temperature point to a significant degree of energy transfer from ruthenium to osmium states in the polymer.
