The present invention is directed toward the preparation of novel polysubstituted fullerenes. The method of forming polysubstituted fullerenes comprises contacting a fullerene with an electrophilic reagent selected from the group consisting of nitronium ion and organic peracid, provided that when the electrophilic reagent is nitronium ion, the fullerene is subsequently contacted with a nucleophilic reagent.
