Fine whiskers of a C60 derivative, i.e., C60 monosubstituted by ethyl ester of malonic acid, C60[C(COOC2H5)2], were fabricated for the first time using a system of toluene with concentrated C60[C(COOC2H5)2] and isopropyl alcohol. The center-to-center distance of C60[C(COOC2H5)2] molecules along the close-packed direction of the C60[C(COOC2H5)2] whiskers was in the same range as that of the C60 nanowhiskers prepared by the same method. The C60[C(COOC2H5)2] whiskers were assumed to take body-centered tetragonal or hexagonal close-packed crystal structures. The C60[C(COOC2H5)2] whiskers showed a high density of stacking faults. The C60[C(COOC2H5)2] whiskers with the growth direction different from the C60 whiskers were observed.
