Abstract

Abstract: The change of absorption spectrum of meso-tetra(4-sulfophenyl)porphyrin (TPPS)in micelles, PrOH and KCl aqueous solution was studied. The dimerization constant K_D and rate constant k of dimerization reaction of TPPS were measured. It was shown that the K_D of TPPS is decreased in micelles and PrOH-H₂O solution and increased in KCl solution as compared with that in aqueous solution.

Key words: TPPS, Micelles, Dimerization constant, Dimerization Kinetics
