Abstract
Three kinds of cationic porphyrins have been employed to study intermolecular interaction of these porphyrins in water. Fluorescence behavior of 4,4',4'',4'''-(21H,23H-porphine-5,10,15,20-tetrayl) tetrakis [1-octylpyridinium] tetrachloride (TOPyP) is essentially the same at that of 4,4',4'',4'''-(21H,23H-porphine-5,10,15,20-tetrayl) tetrakis [1-methylpyridinium] tetrachloride (TMPyP), which has been assumed tor form a dimer in water even at very low concentrations (>2×10 −7 M)
