Abstract:
The complex C60PtP(OPh)3]2 displays C60 ππ* intraligand bands in the UV-Vis region and a long-wavelength absorption at λmax = 770 nm which is assigned to a metal-to-ligand charge transfer (MLCT) transition from platinum to fullerene. The irradiation of the complex leads to the population of the reactive MLCT state and subsequently to the dissociation (C60PtP(OPh)3]2 → C60 + PtP(OPh)3]2) in the primary photochemical step. Product formation takes place by the interception of PtP(OPh)3]2 with suitable scavengers such as CHCl3 or O2.
