Recent Synthetic Methods towards Graphdiyne

Graphdiyne (GDY) is an exclusive carbon allotrope with a two‐dimensional (2D) structure that can be synthesized in laboratory settings. Due to its distinctive 2D structure and excellent electronic properties, GDY has captured the great interest of researchers. In addition, the porous nature and high specific surface area of GDY afford numerous storage sites and channels, rendering it highly promising for diverse applications. The synthesis of GDY still faces a multitude of obstacles and challenges. Developing new synthesis methods towards high‐quality GDY is particularly significant. As such, we here presented an overview of the reported synthesis techniques for GDY, categorizing them into three distinct approaches: interfacial synthesis, solid‐phase synthesis, and solution‐phase synthesis. This comprehensive summary provides valuable references for addressing the persistent challenges in the synthesis of GDY. In the end, an outlook sheds light on future research of the GDY materials.
