Four novel [60]fullerene pyrrolidines containing trifluoromethyl (CF 3 ) group have been synthesized via 1,3‐dipolar cycloaddition reaction, which have been characterized by UV‐Vis spectroscopy, fourier transform infrared spectroscopy, matrix‐assisted laser desorption ionization‐time of flight mass spectroscopy, and 1 H, 13 C, 19 F nuclear magnetic resonance spectrometer ( 1 H NMR, 13 C NMR, 19 F NMR). Their optical and electrochemical properties have been studied, and the results show that those fulleropyrrolidines containing CF 3 group have good fluorescence and electrochemical properties. Compared with C 60 , 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‐C 61 ‐butyric acid methyl ester.
