Synthesis and characterization of physical, electronic, and photochemical aspects of 9,10-phenanthrenequinonediimine complexes of ruthenium(II) and rhodium(III)

Abstract

A series of ruthenium(II) and rhodium(III) complexes containing the novel 9,10-phenanthrenequinone diimine (phi) ligand have been prepared and characterized with respect to structure, spectroscopy, and/or photochemical reactivity. Synthetic approaches to mixed-ligand complexes containing the phi ligand include direct addition of the protected N,N'-bis(trimethylsilyl)-phenanthrenequinone diimine ligand to the metal center of chelation first of diaminopohenanthrene followed by oxidation to the coordinated phi ligand
