China's first successful synthesis of graphite alkyne

Graphite alkyne is a new carbon allotrope. Its abundant carbon chemical bonds, large conjugate system, wide surface spacing, excellent chemical stability and semiconducting properties have always attracted the attention of scientists. With fullerene, carbon tube and graphene and other carbon materials have been successfully prepared by physical methods, how to prepare graphite alkyne has always been the focus of scientific research. In recent years, Li Yuliang, a researcher at the Laboratory of Organic Solid State Key Laboratory of Chemistry, Chinese Academy of Sciences, led the team to synthesize two-dimensional carbon with intrinsic band gap sp hybridization on the copper surface from the perspective of surface chemical reaction and solid-state growth synthesis chemistry Of the new allotrope graphite alkyne, has opened up a precedent for the artificial synthesis of carbon allotrope. Large area graphite alkyne film Macro-preparation of high-purity graphite alkyne 90s of last century, the Chinese Academy of Sciences Institute of organic solid-organic laboratories in the Chinese Academy of Sciences under the leadership of Zhu Daoben launched a carbon material fullerenes. According to reports, carbon has sp3, sp2 and sp three kinds of hybrid state, through the different hybrid state can form a variety of carbon allotropes. For example, diamond can be formed by sp3 hybridization, and carbon nanotubes, fullerenes and graphene can be formed by sp3 and sp2 hybridization. Because of their linear structure, cis-trans isomer, and high conjugation, carbon-carbon triple bonds with sp hybrid states have long been eager to obtain new allotropes of carbon with sp hybrid states, Class carbon materials have excellent electrical, optical and optoelectronic properties and will be the key material for the next generation of new electronic and optoelectronic devices.
