Graphynes (GYs), as a novel carbon allotrope, are composed of sp- and sp2-hybridized atoms. Among them, graphdiyne (GDY) is the most widely studied has received great attention. Its unique sp-hybridization, uniform pores, highly conjugated structures, especially GDY with high crystallinity, bring excellent electronic, optic, mechanical characteristics, making them extensively used in electronic devices, energy storage conversion, catalysis, gas separation, seawater desalination, so on. However, materials still face challenges, including synthesis crystalline rapid non-destructive characterization methods. In this review, we primarily summarize design, synthesis, structural high-crystallinity GDY. Various applications also described, which may new opportunities for single-crystalline materials.
