Problems solved by technology

However, there are two problems in the application of graphdiyne in batteries. First, the pore size of graphdiyne itself is small, and Bernal accumulation is easy to occur, which makes the pores in the two-dimensional structure easy to block, thereby inhibiting the diffusion of ions and storage
Second, graphdiyne is an all-carbon material with low energy density

Embodiment 1

[0030] At 6 °C, add 0.4 mL tetrabutylammonium fluoride (TBAF) (1 mol / L THF solution, 0.4 mmol) to a tetrahydrofuran (THF) solution containing 56 mg (0.133 mmol) of compound 2, and The reaction was stirred for 30 minutes. The subsequent reaction product was diluted with dichloromethane, washed with water, dried over anhydrous sodium sulfate, and dried by rotary evaporation to obtain chlorotriynylbenzene (compound 3) (15 mg, 75%). Dissolve compound 3 with 25 mL of pyridine, and slowly add it dropwise to a container containing 50-200 mL of pyridine and 50-300 cm under the protection of argon. 2 In a two-neck bottle with a copper base, the reaction temperature is 50-180° C., and the dropping time is 6-24 hours. Then, the stirring reaction was continued at 50-180°C for 3-5 days. After the reaction, a brown-black film was formed on the copper sheet, and the brown-black transparent film was obtained after the copper sheet was corroded by hydrochloric acid, which was the new chlorin...

Abstract

The invention belongs to the field of material application, and particularly relates to a novel halogen containing carbon-enriched material and application thereof. The material is composed of benzene rings and acetylene bonds, a meta-position of the benzene rings is connected with the acetylene bonds, two acetylene bonds exist between the benzene rings, and other three meta-positions of the benzene rings are connected with halogen. A crystal structure of a thin film with the structure is two-dimensional, a three-dimensional thin film is assembled through interlayer acting force, and the material has potential application prospect in the field of energy-storage devices.

Description

technical field [0001] The invention belongs to the field of material application, and in particular relates to a novel halogen-containing or pseudo-halogen carbon-rich material and its application. Background technique [0002] Since the discovery of graphene as a single-layer 2D crystal in 2004, 2D materials have attracted much attention in the past decade. Because two-dimensional materials usually have the advantages of large specific surface area, good chemical stability, high electrical and thermal conductivity, flexibility and controllable thickness, they are widely used in optoelectronics, spintronics, catalysis, chemical and biological sensors. , supercapacitors, solar cells, and lithium-ion secondary batteries have shown excellent performance (F. Bonaccorso, L.Colombo, G. Yu, M. Stoller, V. Tozzini, A. C. Ferrari, R. S. Ruoff, V.Pellegrini, Science 2015, 347, 1246501.). At present, the synthesis method of two-dimensional materials still mainly adopts the method of...
