[Mechanism of photoregeneration of reduced porphyrin in the presence of oxygen].
Photooxidation of reduced forms of porphyrines (IIH2) was studied. It has been shown that photooxidation of IIH2 is sensitized by initial porphyrine formed in the course of the reaction. Singlet oxygen serves as the basic oxidizer. It is also informed that the search of metastable states of photoreduced anion forms of the pigments by means of flashphotolysis turned to be unsuccessful.
