Diacetylenic linkages
Webdiacetylenic linkages ( C C C C , sp-hybridized C).[37–39] Recently, N-doped graphdiynes emerged as promising ORR metal-free catalysts, with low overpotential, small crossover effect, and long-term stability.[40–42] For example, Liu et[43] al. prepared N-doped graphdiyne by heating graphdiyne under high-purity ammonia mixed with argon. WebFeb 10, 2024 · Graphidyne is a two-dimensional (2D) network of interconnected benzene rings, each joined together by diacetylenic linkages (two carbon-carbon triple bonds connected by a single carbon-carbon bond). Graphene, its well-known cousin, has been used for various applications including the formation of carbon nanotubes and has …
