The synthesis and characterization of multimetallic ruthenium(II) homooligomer complexes containing both pi donor and pi acceptor ligands has been completed. We have also completed photophycial studies of a large number of mononuclear ruthenium(II) mixed ligand complexes that contained both monodentate and bidentate ligands. Also, methodology has been developed for synthesizing bimetallic rhenium(I)/rhenium(I) and ruthenium(II)/rhenium(I) complexes with attached electron donor and electron acceptor ligands. The photophysics of these complexes is currently being explored. New ligand systems have been synthesized. New metal systems have also been investigated. Both cobalt and chronium complexes of heterocyclic ligands have been synthesized. A new platinum(II)/ruthenium(II) complex has been obtained which contains two platinum centers and one ruthenium center. The complex is paramagnetic and we postulate that one platinum is in the +1 oxidation state and the other is in the +2 state. In addition we have expanded our efforts to include A-frame rhodium binuclear complexes. These complexes luminesce weakly and have short-lived exicted states. 3 figs.
