Summarize this article for a 10 year old
Graphyne is an allotrope of carbon. Its structure is one-atom-thick planar sheets of sp and sp2-bonded carbon atoms arranged in crystal lattice. It can be seen as a lattice of benzene rings connected by acetylene bonds. The material is called graphyne-n when benzene rings are connected by n sequential acetylene molecules, and graphdiyne for a particular case of n = 2 (diacetylene links).

Depending on the content of acetylene groups, graphyne can be considered a mixed hybridization, spk, where k can be 1 or 2,[1][2] and thus differs from the hybridization of graphene (considered pure sp2) and diamond (pure sp3).
First-principles calculations showed that periodic graphyne structures and their boron nitride analogues are stable. The calculations used phonon dispersion curves and ab-initio finite temperature, quantum mechanical molecular dynamics simulations.[3]
