Photophysics and Photochemistry of Tris(2,2'-Bipyridyl) Ruthenium(II) Within the Layered Inorganic Solid Zirconium Phosphate Sulfophenylphosphonate.

摘要

The photophysics and photochemistry of tris(2,2-bipyridyl) ruthenium(II) (Ru(bpy)3) 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. Albery's 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 Ru(bpy)3 in ZrPS via a combined dynamic and quasi static (sphere of action) quenching mechanism. Keywords: Photophysics, Photochemistry, Tris(2-Bipyridyl), Rthenium(II), Zirconium, Phosphate, Sulfophenylphosphonate.
