    • Abstract

       

      The quenching rate constants,kq, for the excited state electron transfer reactions oftris(2,2′-bipyridine)chromium(III) ion with several aryl methyl sulphides (ArSMe) obtained by the luminescence quenching technique, are accelerated by electron releasing groups and retarded by electron withdrawing groups present in the aryl moiety of ArSMe. The plot ofRT Inkq vs.E1/2 values of different sulphides is linear, indicating the electron transfer nature of the reaction. Studies with alkyl phenyl sulphides demonstrate the importance of the steric effect in these photoredox reactions.
