Although methods for a periodic perforation and heteroatom doping of graphene sheets have been developed, patterning closely spaced holes on the nanoscale in graphene nanoribbons is still a challenging task. In this work, nitrogen-doped porous graphene nanoribbons (N-GNRs) were synthesized on Ag(111) using a silver-assisted Ullmann polymerization of brominated tetrabenzophenazine. Insights into the hierarchical reaction pathways from single molecules towards the formation of one-dimensional organometallic complexes and N-GNRs are gained by a combination of scanning tunneling microscopy (STM), atomic force microscopy (AFM) with CO-tip, scanning tunneling spectroscopy (STS) and density functional theory (DFT).

自下而上合成氮掺杂多孔石墨烯纳米带

尽管已经开发了石墨烯片的周期性穿孔和杂原子掺杂的方法，但在石墨烯纳米带中在纳米尺度上图案化紧密间隔的孔仍然是一项具有挑战性的任务。在这项工作中，使用银辅助的溴化四苯吩嗪的 Ullmann 聚合在 Ag(111) 上合成了氮掺杂的多孔石墨烯纳米带 (N-GNRs)。通过结合扫描隧道显微镜 (STM)、原子力显微镜 (AFM) 与 CO-tip、扫描隧道光谱，可以深入了解从单分子到形成一维有机金属配合物和 N-GNR 的分级反应途径。 STS）和密度泛函理论（DFT）。
