Four novel [60]fullerene pyrrolidines containing trifluoromethyl （--CF3） group have been synthesized via 1,3-dipolar cycloaddition reaction, which have been characterized by UV-Vis spectroscopy, fourier transform in- frared spectroscopy, matrix-assisted laser desorption ionization-time of flight mass spectroscopy, and IH, 13C, 19F nuclear magnetic resonance spectrometer （IH NMR, 13C NMR, 19F NMR）. Their optical and electrochemical prop- erties have been studied, and the results show that those fulleropyrrolidines containing --CF3 group have good fluo- rescence and electrochemical properties. Compared with C60, they have negative shifts in varying degrees for half-wave potentials, and may have potential applications for photovoltaic conversion materials since their lowest unoccupied molecular orbital （LUMO） levels are close to that of [6,6]-phenyl-C6：butyric acid methyl ester.
