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.
