Abstract:
We compare the photostability of one porphyrin and two chlorine photosensitizers. We show that a higher photostability of dimegine compared to photoditazine and radachlorin is determined both by their different chemical natures and by the fact that the aggregation ability of porphyrin dyes is higher than that of chlorine dyes, which in the solution leads to efficient formation of dimers and higher-order complexes.
