On-Surface Synthesis of Carbon Nanostructures

Abstract

Novel carbon nanomaterials have aroused significant interest owing to their prospects in various technological applications. The recently developed on-surface synthesis strategy provides a route toward atomically precise fabrication of nanostructures, which paves the way to functional molecular nanostructures in a controlled fashion. A plethora of low-dimensional nanostructures, challenging to traditional solution chemistry, have been recently fabricated. Within the last few decades, an increasing interest and flourishing studies on the fabrication of novel low-dimensional carbon nanostructures using on-surface synthesis strategies have been witnessed. In particular, carbon materials, including fullerene, carbon nanotubes, and graphene nanoribbons, are synthesized with atomic precision by such bottom-up methods. Herein, starting from the basic concepts and progress made in the field of on-surface synthesis, the recent developments of atomically precise fabrication of low-dimensional carbon nanostructures are reviewed.

A series of recently reported on-surface syntheses of low-dimensional carbon nanostructures with atomic precision is reviewed and summarized, including graphene-derived nanostructures and the emerging carbon nanostructures with acetylenic scaffolding (i.e., metalated carbyne). It is hoped that this on-surface synthesis strategy will continue to push the boundaries of organic chemistry, surface science, and materials science.
