Complexes of ruthenium(II) with the polypyridyl ligands dipyrido(3,2-a:2',3'-c)phenazine, the 9-phenyldipyrido (3,2-a:2',3'-c)phenazinium cation, 4,7-dichloro-1,10-phenanthroline, and 4,7-bis(dicyanomethylidene)-1,4,7,10-tetrahydro-1,10-phenanthroline (BDCMP) have been prepared and their UV/visible absorption and emission characteristics determined. Electrochemical, infrared, and NMR results have also been obtained for several of the complexes. The results of these studies indicate the existence of a weakly coupled bichromophoric system for the two dipyridophenazine complexes, with almost independent Ru/sup II/(bpy)/sub 3/- and phenazine-like chromophore units. In the case of the BDCMP complexes, a substantially modified Ru/sup II/(phen)/sub 3/ ..pi..-electron system is indicated with evidence of both strong sigma-donor and ..pi..-acceptor character for the coordinated BDCMP ligand.
