Polysubstituted fullerenes and their preparation.

摘要

One embodiment of the present invention is directed to polysubstituted fullerene moieties having a plurality of substituents thereon, selected from hydroxy, oxide, nitro, amino, organocarboxy, amide, and mixtures thereof. Another embodiment is directed toward the preparation of the novel polysubstituted fullerenes which method comprises contacting fullerenes with an electrophilic reagent such as nitronium ion or an organic peracid. When the electrophilic agent is nitronium ion, the fullerene is further contacted with a nucleophilic reagent. The polysubstituted fullerenes are particularly useful as cross-linking agents in polymers and/or as core building blocks of star polymers.
