A series of derivatives of 5,10,15,20-tetrakis-(4-N-methylpyridyl)-porphine, where one N-methyl group was replaced by a hydrocarbon chain ranging from C6 to C22, were characterized for their photophysical and photosensitizing properties. The absorpti

In the separated surface-sensitizer system, a photosensitizer is physically separated from the substrate by a thin air layer under such conditions that only singlet oxygen can reach and oxidize the substrate, preventing the competition by type I phot
