Problems solved by technology

However, the synthesis of this type of material is carried out under high-temperature ion thermal conditions, which need to be carried out at 400-700 degrees Celsius, and the reaction time needs to be more than 20 hours, and even several days under some conditions. Therefore, using this high-temperature ion thermal method to synthesize nano Porous triazine-based covalently bonded organic framework materials require high production equipment, high production energy consumption, low production efficiency, and high production costs

Embodiment 1

[0034] Weigh 2.02g (0.0158mol) of terephthalonitrile, then weigh 16.02g (0.118mol) of anhydrous zinc chloride, mix thoroughly and place in a 25ml crucible, then put the crucible with the reaction mixture into the microwave reactor (P70D20SP-DF, China Shenzhen Galanz Co., Ltd.) tray, the output power is 280W. The reaction vessel was reacted under microwave irradiation for 30 minutes, the reaction was stopped, and cooled to room temperature. Soak the resulting reaction mixture in 0.1mol / L hydrochloric acid for 3 hours, filter it with suction, wash it with dilute hydrochloric acid, stir it with dilute hydrochloric acid for 12 hours, filter it with suction again, wash it with deionized water and tetrahydrofuran, and then put the product into a vacuum drying oven Dry at 150 degrees Celsius for 4 hours under the condition of vacuum degree 0.0095Mpa.

Abstract

The invention relates to a quick synthesizing method of a triazinyl organic framework material with nano pores, a triazinyl organic oligomer and a triazinyl organic compound and application thereof. In the presence of a Lewis acid as well as in the presence that an inorganic salt fusing assistant exists or does no exist in at least one single nitrile-based and / or multi-nitrile-based organic compound and under the condition of microwave radiation, the covalent bond organic framework material with a triazinyl structure and nano pores, the triazinyl organic oligomer or the triazinyl organic compound is generated, wherein pores or channels which are positioned in at least one direction in space and have size of over 0.3nm are arranged inside the obtained triazinyl covalent bond organic framework solid. The method provided by the invention has the advantages of short required synthesis time, high production efficiency and low production energy consumption; and the products have wide application range.

Description

technical field [0001] The invention belongs to a nano-hole triazine-based covalent bond organic framework material, a triazine-based organic oligomer, and a rapid synthesis method of a triazine-based organic compound and an application thereof. Background technique [0002] Nanoporous covalent organic framework materials are a new class of porous materials, which are different from metal organic framework materials, another new type of porous materials that have been developed rapidly in recent years. Covalent organic frameworks are formed by covalent bonds, including H, C, O, B and other elements. Compared with other porous materials, covalent organic framework materials have the characteristics of lower density, higher specific surface area, and better thermal stability (thermal stability can reach 500°C). [0003] There have been some literature reports on the synthesis and application of nanoporous covalent organic framework materials, such as Mastalerz M. et al. in An...
