摘要

摘要Au（111）上的分子内甲基-甲基偶联被探索为石墨烯纳米带（GNRs）边缘扩展的一种新的表面协议。通过高分辨率扫描隧道显微镜、非接触原子力显微镜和拉曼光谱表征，甲基-甲基偶联确实在GNR的扶手椅边缘进行，形成具有sp3-或sp2-杂化碳的六元环。

Exploring Intramolecular Methyl–Methyl Coupling on a Metal Surface for Edge-Extended Graphene Nanoribbons

Abstract Intramolecular methyl–methyl coupling on Au (111) is explored as a new on-surface protocol for edge extension in graphene nanoribbons (GNRs). Characterized by high-resolution scanning tunneling microscopy, noncontact atomic force microscopy, and Raman spectroscopy, the methyl–methyl coupling is proven to indeed proceed at the armchair edges of the GNRs, forming six-membered rings with sp3- or sp2-hybridized carbons.
