ABSTRACT:
A fullerene derivative, with a solubility in n-hexane of not lower that 0.1 mg/ml at 25° C., includes a fullerene skeleton and three or more organic groups attached to the fullerene skeleton, where each of the organic groups is represented by the general formula (III):in-line-formulae description="In-line Formulae" end="lead"?—CH2—X (R2)(R3)(R4)  (III)in-line-formulae description="In-line Formulae" end="tail"?where X represents an element belonging to the group 14 in the periodic table; and R2, R3and R4may be the same or different and each represents a hydrogen atom, hydrocarbon group, alkoxy group or amino group.
