Correlations between electrochemical potentials and optical charge transfer energies in ruthenium bipyridine derivatives

Linear relationships are discussed linking the Ru → π *(bpy) charge transfer transition energy in the species [Ru(bipyridine) 2XY] n+ (X, Y various non-diimine ligands, n = 0, 1, 2) and the observed potentials E[Ru(III/Ru(II)], E[(bpy)/(bpy −)] and their difference. The conditions under which such r...

More Information
Summary:Linear relationships are discussed linking the Ru → π *(bpy) charge transfer transition energy in the species [Ru(bipyridine) 2XY] n+ (X, Y various non-diimine ligands, n = 0, 1, 2) and the observed potentials E[Ru(III/Ru(II)], E[(bpy)/(bpy −)] and their difference. The conditions under which such relationships might be valid are investigated. Correlation of E[Ru(III)/Ru(II)] with E[(bpy)/(bpy −)] is also explored. The results permit the use of optical energies to calculate CT energies and vice versa.
