Embodiment 1

[0025] The preparation method of the zinc phthalocyanine-pyrene-covalent organic framework / single-walled carbon nanotube composite provided in this example is as follows:

[0026] Step 1, get 7.1mg of zinc octahydroxyphthalocyanine, 5.8mg of 2,7-pyrene diboronic acid, 5mg of single-walled carbon nanotubes, add 1ml of dimethylacetamide (DMAc) and 1ml of o-dichlorobenzene ( o-DCB) solvent, put into a heat-resistant glass reaction tube of 10ml, and ultrasonically disperse for 10 minutes to form suspension A;

[0027] Step 2: Suspension A was subjected to liquid nitrogen freezing-vacuumizing-degassing steps three times, sealed, and reacted at 130° C. for 96 hours to obtain crude product B.

[0028] Step 3, after centrifuging the crude product B, wash twice with 2ml of dimethylacetamide and 2ml of acetone solvent respectively, and dry to obtain zinc phthalocyanine-pyrene-covalent organic framework / single-walled carbon nanotube composite.

Abstract

The invention relates to a preparation method of a zinc phthalocyanine-pyrene-covalent organic frame / single wall carbon nanotube composite. The preparation method comprises the following steps: step one, adding octahydroxy zinc phthalocyanine, 2,7-pyrenyl hypoboric acid, and single wall carbon nanotube into a mixture of dimethyl acetamide and o-dichlorobenzene, filling the mixture into a heatproof glass reaction tube, dispersing the mixture by ultrasonic waves to obtain a suspension A; step two, carrying out the following steps for at least three times: freezing by liquid nitrogen, vacummizing, and degassing, then sealing the tube, carrying out reactions at a certain temperature for a while so as to obtain a coarse product B; step three, subjecting the coarse product B to centrifugation, washing the coarse product B with a specific solvent for two times, and drying so as to obtain the final product. The provided method is pollution-free, the equipment requirement is simple, the reaction conditions are mild, and the method is suitable for industrial massive production.

Description

technical field [0001] The invention relates to a preparation method in the technical field of composite materials, in particular to a zinc phthalocyanine-pyrene-covalent organic framework / single-wall carbon nanotube composite. 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 crystallini...
