Abstract
We report a chemical route to synthesize centimeter-scale stoichiometric "graphenol (C<sub>6</sub>OH<sub>1</sub>)", a 2D crystalline alcohol, via vapor phase hydroxylation of epitaxial graphene on Cu(111). Atomic resolution scanning tunneling microscopy revealed this highly-ordered configuration of graphenol and low energy electron diffraction studies on a large-area single crystal graphene film demonstrated the feasibility of the same superstructure being achieved at the centimeter length scale. Periodic density functional theory (DFT) calculations about the formation of C6(OH)<sub>1</sub> and its electronic structure are also reported.
