Oxo-graphene nanoribbons (oxo-GNRs) can be prepared by the oxidative unzipping of single-walled carbon nanotubes. We present an orthogonal functionalization method for the functionalization of the rims and the π-surface, respectively, what is only possible due to the high rim portion in oxo-GNRs. In particular, X-ray photoelectron spectroscopy could be used to follow the reaction and detect the marker atoms contained in the addends. We propose that the reported orthogonal functionalization strategy can also be applied on other oxo-functionalized carbon materials, such as graphene quantum dots, or reduced graphene oxide flakes.
含氧石墨烯纳米带（oxo-GNRs）可通过单壁碳纳米管的氧化解链制备。我们提出了一种正交功能化方法，分别对边缘和π表面进行功能化，这仅因oxo-GNRs中较高的边缘部分才得以实现。特别是，X射线光电子能谱可用于跟踪反应并检测加成物中所含的标记原子。我们认为，所报道的正交功能化策略也可应用于其他含氧官能化的碳材料，如石墨烯量子点或还原氧化石墨烯薄片。
