Abstract: While the intercalation of C60 and the formation of C 60 - in the supercages of NaX and NaY are confirmed by using 129Xe NMR and ESR, the photophysical properties of C60 and C 60 - are characterized by monitoring transient reflectance spectra and kinetics, fluorescence kinetics, and diffuse reflectance spectra. C 60 - is considerably more abundant in NaY than in NaX. This difference is explained in terms of polarity difference between two zeolites. Both C60 and C 60 - have remarkably elongated excited-state lifetimes due to their collision-free environment in zeolitic nanocavities although C 60 - has much shorter lifetimes than C60. C 60 - , in particular, shows intense absorption and emission due to its reduced symmetry in zeolites.
