Abstract
A fullerene derivative represented by the following formula (1): wherein “FLN” represents a fullerene core, R1 represents an optionally substituted C1-C24 alkyl group or an optionally substituted C7-C24 aralkyl group, R2 and R3 independently represent a hydrogen atom or an optionally substituted C1-C24 hydrocarbon group but excluding a case where both of R2 and R3 are hydrogen atoms, and R2 and R3 may combine together to form a ring.
