Synthesis of Amphiphilic Surfactants Containing Porphyrin and Their Photosensitizing Effect on the Reduction of Fast Red A by Ascorbic Acid

Abstract

Amphiphilic surfactants containing porphyrin with one or four poly(oxyethylene) chains were prepared by an immortal_polymerization. The photosensitizing effect of these polymers on the oxidation-reduction of L-ascorbic acid and Fast Red A(FRA) was examined in acetate buffer solution. The polymer having four poly(oxethylene) chains photosensitized the reduction better than the polymer with one poly(oxyethylene) chain which formed association. The effects of pH and of surfactant concentration on the photosensitized reaction were examined.
