Synthesis of graphyne
WebAug 29, 2024 · γ-Graphyne is an emerging carbon allotrope, and synthesis of large-size atomically precise γ-graphyne fragments would be crucial to understand its distinctive properties. Herein, a long-sought-after graphyne spoked wheel with 6-fold symmetry was synthesized mainly through cobalt(0)-catalyzed cyclotrimerization of a triyne intermediate … Graphyne was first theoretically proposed by Baughman et al. in 1987. In 2010, Li et al. developed the first successful methodology for creating graphdiyne films using the Glaser–Hay cross-coupling reaction with hexaethynylbenzene. The proposed approach makes it possible to synthesize nanometer-scale graphdiyne and graphtetrayne, which lack long-range order. In 2024, Cui and co-workers reported on a mechanochemical technique for obtaining graphyne using ben…
