Abstract

Experimental studies on the luminescent properties of ruthenium based complexes have shown an excited state lifetime dependence on the solvent and temperature. An activation energy for the metal to ligand charge transfer (MLCT) based luminescence decay properties of tris(2,2'-bipyridine)ruthenium(II) chloride has been determined in various solvents. The results indicate a solvent influence on this decay. A model is being developed to correlate the lifetimes with interactions of the chromophore with the solvent to aid in the development of future sensors.
