ABSTRACT:
The invention relates to fullerene derivatives which are capable of scavenging free radicals. The derivatives have the formula F(--X).sub.m (--Y--Z).sub.n, in which F is a fullerene core; each X is independently --CO.sub.2.sup.-, --SO.sub.3.sup.-, --SH, or the like; each --Y--Z is independently (C.sub.3-30 alkyl ether).sub.50 --CH.sub.2 --CO.sub.2.sup.-, (C.sub.3-30 alkyl ester).sub.50 --CH.sub.2 --SO.sub.3.sup.-, (C.sub.3-30 alkyl amide).sub.50 --CH.sub.2 --SH, or the like; m is 0-30; n is 0-30; and the sum of m and n is 2-30.
