Correlations between Electrochemical Potentials and Optical Charge Transfer Energies in Ruthenium Bipyridine Derivatives

摘要

Linear relationships are discussed linking the Ru yields Pi*(byp) 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)) is also explored. The results permit the use of optical energies to calculate CT energies and vice versa.
