Abstract
A phenomenological model is developed describing the kinetics of fast intramicellar redox reactions induced by light. It takes into account the influence of compartmentation as well as statistical distribution of reactants which lead to kinetic equations that differ from the rate laws in homogeneous kinetics. The theoretical predictions are experimentally tested by laser photolysis studies with solutions containing tetradecyltrioxyethylene sulfate as the micelle forming agent, N-methyl-phenothiazine (MPTH) as an electron donor, and tris(2,2-bipyridine) -ruthenium(II) [Ru(bipy)2+3], as an electron acceptor. The intramicellar electron transfer from MPTH to excited state Ru(bipy)2+3 occurs with a specific rate of 3×106 s−1. This reaction is followed by a back electron transfer occuring with a specific rate of 6×106 s−1. Possible ways to intercept the back reaction and to achieve light energy storage effects are indicated.
