A method for synthesizing compounds of the formula n where C 60 is a C 60 fullerene. The method comprises the steps of forming a macrocyclic malonate compound of the formula n where each Z is the same or different and is a straight-chain or branched-chain aliphatic radical having from 1-30 carbon atoms which may be unsubstituted or monosubstituted or polysubstituted by identical or different substitutents, in which radicals up to every third CH 2 unit can be replaced by O or NR where R is alkyl having 1-20 carbon atoms or a chain containing unsubstituted or substituted aryl or other cyclic groups and n is an integer from 2 to 10; reacting said macrocyclic malonate compound with C 60 to form an adduct of the formula n where the Z radicals are linked together to form said macrocycle adduct; and hydrolyzing said macrocycle adduct to form a compound of the formula |
