Abstract

The Surface‐enhanced Raman spectra of Co(III)TMPyP(4)Cl and Mn(III)TMPyP(4)Cl [where TMPyP(4) = tetrakis (4‐N‐methylpyridyl)porphyrin] demonstrate the formation of Ag(II)TMPyP(4) on the silver surface. The reaction is not photon assisted but is dependent on the sol activity and time. The effect of NaCl on the sol activity and the surface‐induced reaction was investigated. It was observed that the metal substitution reaction of Mn(III)TMPyP(4)Cl was more efficient than that of Co(III)TMPyP(4)Cl.
