Patent ID: 8039681

Claim:
A fullerene molecule comprising n carbon atoms wherein m groups described generally by the formula —C(F 2 )—C(−)(F)—O a —[C(F 2 )—C(F)(R)] b—O c—[C(F 2 )] d -T are each covalently bonded to the fullerene through formation of a 4-member ring with the unsaturated pi system of the fullerene; and wherein a is 0 or 1; b is 0 to 10; c is 0 or 1; d is 1 to 10; each R is independently selected from the group consisting of H, F, methyl, branched or straight-chain perfluorinated C 1 -C 10 alkyl, phenyl and perfluorinated aryl groups; each T is independently selected from the group consisting of —CO 2 H, —SO 3 H, —SO 2 NH 2 , —SO 2 NHSO 2 J and —PO 3 H 2 groups; each J is independently selected from the group consisting of F, methyl, branched or straight-chain perfluorinated C 1 -C 10 alkyl, phenyl and perfluorinated aryl groups; n is an integer from 20 to 1000; and m is an integer from 1 to n/2 when n is an even integer, or is an integer from 1 to (n−1)/2 when n is an odd integer.
