Fullerene derivatives of the formula I (See formula I) where the symbols and indices have the following meanings: F: is a fullerene radical of the formula C(20=2m) where m = 20, 25, 28, 29; E1, E2: are identical or different and are each COOH, COOR, CONRR1, CHO, COR, CN, P(O)(OR)2 and SO2R, where R, R1 are each a straight-chain or branched, aliphatic radical (C1 to C20) which may be unsubstituted or monosubstituted or polysubstituted by identical or different substituents, in which radical up to every third CH2 unit can be replaced by O or NR4, where R4 is (C1-C20) -alkyl or benzyl, or a benzyl radical or phenyl radical which can be unsubstituted or substituted by from 1 to 5 substituents R, OH, OR, COOR, OCOR, SO3H, SO2Cl, F, Cl, Br, NO2 and CN or together are (See formula II) or are different from one another and are each COR, R or H, or are different from one another and are each COR/R or F/Cl/Br, where R is as defined above, or are different from one another and are each NO2, R3 or H, where R3 is an unsubstituted, mono- substituted or polysubstituted aliphatic radical (C1 to C20); n: is a natural number from 1 to 10 + m where m = 20, 25, 28, 29.
