Changes in the axial ligation and ?-cation radical formation of zinc tetraphenylporphin (ZnTPP) in alkyl chlorides as a function of laser power have been probed by the resonance Raman technique.ZnTPP forms weakly bound pentacoordinate species in the ground state at low laser power (< 8 mW at the sample) which dissociate mainly by a thermal process into tetracoordinate, neutral ZnTPP or its ?-radical cation due to electron transfer from excited ZnTPP to CCl4 at higher laser powers.From the dependence of photo-oxidation on the concentration of electron acceptors, excitation wavelength and solvents, it is inferred that a weak triplet exciplex is formed between the excited ZnTPP and electron acceptor which serves as transient species and that light-induced intermolecular charge transfer from ZnTPP to CCl4 is the primary process involved in photo-oxidation.
