The technique of pulse radiolysis was used to investigate the binding of ferrocyanide and ferrocyanide ions to the positive polyelectrolyte polybene in aqueous solutions. This polyelectrolyte was studied in the chemical system using cis-dicyano-bis(2,2'-bipyridine)ruthenium(II) as photosensitizer and Fe(CN)/sub 6//sup 3 -/ as quencher. No net photoelectron transfer was observed in the absence of polybene, but on addition of the polycation the quantum yield of photoelectron-transfer products was nearly unity. The rate of regeneration of the ground-state reactants was about 1 order of magnitude less than diffusion-controlled.
