Abstract: The ability of meso-tetrakis-(substituted phenyl) porphine derivatives for photo-generating singlet oxygen (O2) is studied by ESRspectrometry. The results show that the singlet oxygen yields of most of porphine derivatives are higher than that of HPD. It is also exhibited that the nature and structure of the substituent at the meso position are closely related to the photo-sensitizing ability of meso-tetrakis-(substituted phenyl) porphine.
