Claisen Rearrangement of Graphite Oxide: A Route to Covalently Functionalized Graphenes

摘要

The chemical modification of nano- or micromolecular surfaces is widely used for the precise structural and/or electrical manipulation of bulk materials.'1' In particular, atomically thin graphitic molecules such as fullerenes, carbon nanotubes, and graphene display pronounced physico-chemical and electronic changes after synthetic derivatization of their surfaces. In many cases these graphitic substrates can be imbued with a wide range of desirable attributes such as increased solubility in a specific solvent, enhanced mechanical properties, chemosensing, and conductance changes. As a consequence of these attributes, numerous graphitic derivatives have been utilized in a variety of academic and industrial applications.
