Graphdiyne (GDY) has unique characteristics of a highly conjugated π system, uniformly distributed nanopores and direct band gap. In order to study the intrinsic properties of GDY, the synthesis methods of small‐molecule diyne structure (GDY substructure), one‐dimensional nanoribbons and highly ordered 2D GDY thin films were developed. In the Minireview by Y. Li et al. on page 12310 ff., powerful strategies such as enhancing the chemoselectivity through optimizing interfaces at which coupling reactions take place and the molecular structure of precursors that prefer to form a flat 2D surface upon coupling reactions are highlighted. The obtained structures with different dimensions provide an opportunity to study various physical properties, such as the function of oligomer size, and reveal a reliable correlation between structure and properties.
