New ‘wonder material’ graphyne synthesized in two labs

Two new processes for producing different types of graphyne – a 2D allotrope of carbon that includes triple bonds – have been reported in independent papers. One paper – from researchers in the US and China – reports the first experimental synthesis of a bulk crystal of the most stable form of graphyne, which could potentially have multiple uses. The second – from researchers in South Korea – describes the discovery and synthesis of a hitherto unpredicted “holey graphyne”. However, some scientists are not convinced of the existence of this second type of graphyne. [Lire plus…]
