Pluorescence decay curves for 5,10,15,20-tetrakis(4-sulfonatopheny1)-21H,23H-porphine tetraanion (TPPS4) have been measured in the absence and presence of the methylviologen dication &IV'+) with various ionic strengths in methanol. In the presence of MV2+ the fluorescence decays can be expressed by
