On-Surface Synthesis of Graphyne-Based Nanostructures

Abstract

The successful synthesis of stacking graphdiynes has stimulated numerous fascinating applications. However, it still remains challenging to prepare atomically precise 2D graphdiyne and other graphyne-based structures. The development of on-surface synthesis has contributed to many secondary graphyne-based structures that are directive in fabricating extended graphyne networks. Herein, the recent progress concerning on-surface synthesis of graphyne-based nanostructures, especially atomically precise graphdiyne nanowires, is summarized.

Keywords: graphdiyne; graphyne; nanostructures; on-surface synthesis; scanning tunneling microscopy (STM).
