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 porph...
