The on-surface synthesis of carbon nanostructures has attracted tremendous attention owing to their unique properties and numerous applications in various fields. With the extensive development of scanning tunneling microscope (STM) and noncontact atomic force microscope (nc-AFM), the on-surface fabricated nanostructures so far can be characterized on atomic and even single-bond level. Therefore, various novel low-dimensional carbon nanostructures, challenging to traditional solution chemistry, have been widely studied on surfaces, such as polycyclic aromatic hydrocarbons, graphene nanoribbons, nanoporous graphene, and graphyne/graphdiyne-like nanostructures. In particular, nanostructures containing -hybridized carbons are of great advantage for their structural linearity and small steric demands as well as intriguing electronic and mechanical properties. Herein, the recent developments of low-dimensional -carbon nanostructures fabricated on surfaces will be summarized and discussed.
由于其独特的性质以及在各个领域的众多应用，碳纳米结构的表面合成引起了极大关注。随着扫描隧道显微镜（STM）和非接触原子力显微镜（nc-AFM）的广泛发展，目前表面制备的纳米结构能够在原子甚至单键水平上进行表征。因此，各种对传统溶液化学具有挑战性的新型低维碳纳米结构，已在表面上得到广泛研究，例如多环芳烃、石墨烯纳米带、纳米多孔石墨烯以及类石墨炔/石墨二炔纳米结构。特别地，含有sp-杂化碳的纳米结构因其结构线性、小空间需求以及有趣的电子和机械性能而具有很大优势。在此，将总结并讨论表面制备的低维sp-碳纳米结构的最新进展。
