概要	Two rotaxanes contg. [60]fullerene (C60) as pendants on a crown-ether necklace, to which ferrocene (Fc) as axle stoppers were added, have been synthesized. One rotaxane has an ammonium cation in the center of the axle (C60;Fc)Rot+ and the other has a neutral axle (C60;Fc)Rot. In both rotaxanes, efficient intra-rotaxane photoinduced electron-transfer processes have been obsd. by the selective excitation of C60 which acts as a photosensitized electron acceptor. The rates and efficiencies of the charge-sepn. and charge-recombination processes were evaluated by time-resolved fluorescence and transient absorption measurements with changing solvent polarity. From the different kinetic parameters between (C60;Fc)Rot+ and (C60;Fc)Rot, the light-induced mol. motions of these rotaxanes in the excited states and charge-sepd. states were sep. revealed.
