In SERS-active systems, when a free base porphyrin is adsorbed at a roughened metal surface, the metal ion may be incorporated into the porphyrin core. We have investigated the metalation kinetics of 5,10,15,20-tetrakis(1methyl-4-pyridyl)porphyrin (TMPyP), reÑected in the time evolution of its SERRS
