Abstract

An electron donor-connecting water-soluble porphyrin, meso-(1-pyrenyl)-tris(N-methyl-p-pyridinio)porphyrin, did not demonstrate singlet oxygen generating activity under photo-irradiation. The interaction with DNA successfully recovered the photosensitized singlet oxygen generation by this porphyrin.
