Graphyne is a crystalline form of carbon that is distinct from both diamond and graphite. Unlike diamond, where each atom has four immediate neighbors, or graphite, where each atom has three, graphyne’s structure combines two-coordinate and three-coordinate carbons.
Graphyne is a promising material for future carbon electronics. It has a small band gap of ~0.5 eV, suitable for fabrication of electronic devices. Theoretical models predict ultra-high charge carrier mobility far surpassing that of silicon, and ultimate strength comparable to that of graphene. Chemical modification of graphyne is also easier than that of graphene, which presents significant opportunities for material processing and chip fabrication.
While graphyne was first theoretically predicted more than three decades ago, its synthesis remained elusive. The Rodionov group at CWRU has reported a scalable synthesis of bulk graphyne in 2022 (J. Am. Chem. Soc. 2022, 144, 39, p. 17999).
