The fluorescence and phosphorescence of zinc tetraphenylporphyrin (ZnTPP) and its tetrasulfonated derivative (ZnTPPS) were evaluated using time-resolved luminescence and absorption measurements in three environments: dilute solution, solutions containing polyvinylpyridine (PVP) and quaternary-ammoni
