The photophysics and photochemistry of tris2,2-bipyridyl rutheniumII Rubpy3 absorbed into the layered solid zirconium phosphate sulfophenylphosphonate are described. The decay kinetics of the metal complex are shown to depart from first-order behavior. Alberys model of dispersed kinetics, which assumes a continuous distribution of rate constants, is used to explain the decay kinetics. The oxidative quencher methylviologen MV is shown to react with Rubpy3 in ZrPS via a combined dynamic and quasi static sphere of action quenching mechanism.
