Carborane functionalization of the aromatic network in chemically-synthesized graphene

The conjugated aromatic system of graphene was used to trap the reactive, boron-rich 1,2-carborane cluster. Functionalization of the graphene surface was confirmed by solid-state MAS B-11 NMR spectroscopy and quantified by X-ray photoelectron spectroscopy. This work represents the first confirmed example of direct functionalization of a graphene lattice with carboranes.
