High-yield exfoliation of three-dimensional graphite into two-dimensional graphene-like sheets

Edge-functionalized graphite (EFG) is prepared via a direct'' covalent attachment of organic molecular wedges. The EFG is dispersed in N-methyl-2-pyrrolidone with a concentration as high as 0.27 mg mL(-1), leading to high-yield exfoliation of the three-dimensional graphite into two-dimensional graphene-like sheets.
