We report a chemical route to synthesize centimeter-scale stoichiometric "graphenol (COH)", 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) and its electronic structure are also reported.
我们报道了一种通过在Cu(111)上外延生长的石墨烯进行气相羟基化来合成厘米级化学计量比的二维晶体醇“石墨醇(COH)”的化学方法。原子分辨率扫描隧道显微镜揭示了石墨醇这种高度有序的结构，并且对大面积单晶石墨烯薄膜进行的低能电子衍射研究表明，在厘米长度尺度上实现相同的超结构是可行的。本文还报道了关于C6(OH)形成及其电子结构的周期性密度泛函理论(DFT)计算。
