ㅇPurpose : Organic Synthesis of Graphyne, allotrope of Carbon
- Graphyne is a carbon allotrope which is predicted to have better materials properties than graphene. The paper about its theory and calculating its properties was already reported but it's not synthesized yet.
- In this research, it was synthesized first time using cross coupling with transition metal catalyst and its synthesis steps are effective and short. Also, graphdiyne, which is similar structure to graphyne, was synthesized to gain better electronic properties.



■ Result

ㅇShort and effective synthetic method of monomer to synthesize graphyne was developed.
ㅇGraphyne was synthesized first time in the world using cross-coupling method and was analyzed by using instruments like FT-IR, Raman spectrum, MAS NMR, XRD, SEM.
ㅇGraphdiyne, which is other carbon allotope having triple bonds and benzene rings was synthesized. This is not first synthesis in the world. However, we synthesized diverse structure graphdiyne by changing conditions.
ㅇGraphyne and graphdiyne were analyzed by alpha step and CV instruments to measure electronic properties of them. Especially, the fact graphyne's electronic properties are related to its thickness was confirmed by our research.
ㅇThe research controlling the graphyne's thickness on Cu foil is ongoing by our research team to improve its electronic properties.


■ Expected Contibution

ㅇBecause the graphyne was synthesized by this research successfully, it will be utilized as a new carbon allotope in common with fullerene, carbon nano tube (CNT), and graphene.
ㅇEspecially, when it shows better efficiency than graphene's, it can be utilized not only at academic area like physics, chemistry, and material field but also electonic industry as improved material compared to graphene.
