Abstract

See full text

Provided herein are water-soluble, functionalized fullerenes, and processes for producing water-soluble, functionalized fullerenes. The process includes sulfonating a fullerene in an acidic solution comprising sulfuric acid to produce a sulfonated fullerene, isolating the sulfonated fullerene from the acidic solution without neutralizing the acidic solution, reacting the sulfonated fullerene with hydrogen peroxide to form a reaction product, and isolating a polyhydroxylated fullerene from the reaction product produced from reacting the sulfonated fullerene with the hydrogen peroxide. The process of producing water-soluble fullerenes further includes functionalizing a polyhydroxylated fullerene with one or more pendant functional groups by reacting the polyhydroxylated fullerene with one or more functional group precursors.
