1D and 2D Graphdiynes: Recent Advances on the Synthesis at Interfaces and Potential Nanotechnological Applications

In solution‐based chemistry butadiyne linkage through the homocoupling reaction of alkynes is a versatile tool for the synthesis of π‐conjugated polymers, scaffolds and networks. To date this strategy was actively implemented towards chemical synthesis at interfaces. In this review paper we summarize recent advances in the syntheses of 1D wires, 2D single‐layers and thin films of graphdiyne‐related carbon materials at interfaces and their potential applications in nanotechnology. With a high degree of π‐conjunction, uniformly distributed pores and tunable electronic properties such 2D all‐carbon networks with butadiyne linkages also known as ‘graphdiynes’ have been successfully employed in the field‐effected emission devices, solar cells, for Li ion storage and oil water separation, and as catalysis or chemical sensors.
