Abstract
Pulse radiolysis of aqueous solutions containing (Ir(bpy)/sub 2/(C/sup 3/,H(bpy))/sup 3+ 1,2/ or its basic form (Ir(III)/sup 3 +/ and Ir(III)/sup 2 +/, respectively) in the presence of 2-propanol produces the reduced Ir(II)/sup 2 +/ species (the reduction is at the bpy site). The decay of Ir(II)/sup 2 +/ is strongly enhanced by the presence of small concentrations of poly(styrenesulfonate)(PSS). Both intrapolymer and interpolymer bimolecular reactions of Ir(II)/sup 2 +/ are observed, followed by the formation of a hydride. Exchange of Ir(II)/sup 2 +/ between different polymer molecules is enhanced by ir(II)/sup 2 +/ in the bulk. The effects of (PSS), pulse intensity, and (Ir(III)/sup 2 +/) on the decay kinetics are reported and discussed. The overall effect of PSS on Ir(II)/sup 2 +/ is the catalyzed formation of hydrogen.
