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. Edge-functionalized graphite (EFG) was prepared without creating further defects on the basal plane and it was readily dispersible in common polar solvents.
