[Mechanism of activation of the photosensitizing effect of water-soluble analogs of chlorophyll when bound to a polymer].
It has been shown that the order of mixture of photoreduction components of methylene red with ascorbic acid sensitized with clorine e in an aqueous solution of polyvinilpyrrolidone markedly affects the rate and depth of the reaction. The data obtained support the hypothesis that the intensificiation of the sensitized reaction in the presence of polymer is conditioned by joint polymer binding of the reaction components. This binding facilitates the interaction between the electron donor or acceptor with the light-excited pigment.
