Embodiment 1

[0031] This example provides a method for preparing an alkyne-containing imine bond to connect a covalent organic framework, the steps are as follows:

[0032] Step 1, get 54mg of 2,5-dipropargyloxy terephthalaldehyde (C 14 h 10 o 4 ), 78mg of three (4-aminophenyl) benzene (C 24 h 21 N 3 ), add 5ml of mesitylene / n-butanol / 6mol / L acetic acid (volume ratio: 2:2:1) solvent, put into a heat-resistant glass reaction tube of 10ml, ultrasonically disperse for 5 minutes to form suspension A;

[0033] Step 2: Suspension A undergoes three liquid nitrogen freezing-vacuumizing-degassing steps, seals it and puts it into a microwave reactor, and reacts at 130°C for 2 hours to obtain crude product B;

[0034] Step 3, after the crude product B is centrifuged, the insoluble matter is collected, washed twice with 2ml of n-butanol and 2ml of acetone solvent, and dried to obtain an alkyne-containing imine bond-linked covalent organic framework, such as Figure 5 shown.

Abstract

The invention discloses an imine-bonded covalent organic framework. A preparation method for the covalent organic framework comprises the following steps: adding 2,5-dipropargyl terephthalaldehyde and sym(4-aminophenyl) benzene into a solvent to obtain a mixture, and ultrasonically dispersing the mixture to form a suspension liquid, wherein the solvent is a mixed solvent of sym-trimethylbenzene, n-butyl alcohol and an acetic acid solution; carrying out liquid nitrogen freezing, vacuum-pumping and degassing on the suspension liquid, sealing the suspension liquid, and carrying out a microwave-assisted solvothermal reaction to obtain a crude product; and collecting insoluble substances after centrifuging the crude product, washing and drying the insoluble substances to obtain the imine-bonded covalent organic framework. The preparation method is free of pollution, gentle and simple in reaction conditions, simple in requirements on equipment, and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to a preparation method in the technical field of polymer materials, in particular to an imine bond-linked covalent organic framework and a preparation method thereof. Background technique [0002] Covalent organic frameworks (Covalent Organic Frameworks; COFs) are formed by the connection of organic structural units through covalent bonds. Physical and chemical properties. After searching the literature of the prior art, it was found that in 2012 Donglin JIANG et al. published Covalent Organic Framework (covalent organic framework) on pages 6010-6022 of Volume 41 of "Chemical Society Reviews". Compared with traditional linear and three-dimensional polymers, covalent organic frameworks have completely different structural characteristics. Its atomic layer structure is clear, the connection method is clear, the structural units are arranged regularly, and it has precise periodicity; the material has high crystallinity and can be f...
