Embodiment 1

[0035] Dissolve 10mg of hexaynylbenzene in 25ml of pyridine solution, and slowly add it dropwise to a round-necked flask filled with 50ml of pyridine (pyridine) and 900mg of cuprous iodide under the protection of nitrogen. The temperature of the reaction solution is 60°C. The time is 24 hours. The stirring reaction was then continued at 60°C for 2 days. After the reaction, the reaction was washed three times with ammonia water (AR grade), centrifuged, dried, and ground to obtain a black powder which was a graphyne-like substance. Structural formula such as figure 2 As shown, the preparation process route is as image 3 shown.

Embodiment 2

[0037] Dissolve 10 mg of hexaynylbenzene in 25 ml of pyridine solution, and slowly add it dropwise to a round-necked flask containing 50 ml of pyridine (pyridine) and 800 mg of cuprous iodide (the temperature of the reaction solution is 60°C) under nitrogen protection, and drop Plus time is 24 hours. The stirring reaction was then continued at 60°C for 2 days. After the reaction, the reaction was washed three times with ammonia water (AR grade), centrifuged, dried, and ground to obtain a black powder which was a graphyne-like substance.

Embodiment 3

[0039] Dissolve 10 mg of hexaynylbenzene in 25 ml of pyridine solution, and slowly add it dropwise under nitrogen protection into a round-necked flask containing 50 ml of pyridine (pyridine) and 1000 mg of cuprous iodide (the temperature of the reaction solution is 60 ° C), drop Plus time is 24 hours. The stirring reaction was then continued at 60°C for 2 days. After the reaction, the reaction was washed three times with ammonia water (AR grade), centrifuged, dried, and ground to obtain a black powder which was a graphyne-like substance.

Abstract

The invention relates to a preparation method of a graphdiyne-like substance. The method includes: with cuprous iodide being a substrate, performing a coupling reaction to hexaalkynyl benzene under catalysis by the cuprous iodide in a solvent; removing the cuprous iodide with ammonia water through corrosion, and performing centrifugal separation and drying, and grinding the product to obtain the graphdiyne-like powder product. The method can prepare the graphdiyne-like substance at large scale, shortens the researching period of the graphdiyne in other fields, and makes the graphdiyne possibleto be applied to other fields.

Description

technical field [0001] The invention belongs to the field of semiconductors, in particular to a preparation method of graphyne-like. Background technique [0002] Carbon exists widely on the earth, and due to its unique physical and chemical properties, it is gradually discovered, recognized and utilized by people. Previously, it was believed that carbon had only two isotropes, graphite and diamond. Fullerenes were discovered in 1985 (H.W.Kroto, J.R.Heath, S.C.O'Brien, C / sub 60 / : Buckminsterfullerene, nature, 1985,318:162-163.); Carbon nanotubes were discovered in 1991 (Iijima S . Helical microtubles of graphiticcarbon, Nature, 1991, 354.); In 2004, the two-dimensional carbon-based material graphene was discovered, which greatly enriched the family of carbon materials. With the rapid development of synthetic chemistry, scientists have proposed methods for preparing different carbon allotropes, and also produced some unnatural carbon allotropes. Since graphyne was first pr...
