Embodiment 1

[0025] Benzotrithiophenetrialdehyde (BTT, 10mg, 0.03mmol) and 4,4'-(benzo[C][1,2,5]thiadiazole-4,7-diyl)diphenylamine (Bt, 14.3 mg, 0.045 mmol) into a Pyrex tube (volume about 5 mL, length 20 cm, diameter 1 cm), add 0.5 mL o-dichlorobenzene, 0.5 mL n-butanol and 0.1 mL 6 M acetic acid. The Pyrex tube was then frozen and thawed in liquid nitrogen, evacuated three times to an internal pressure of 1 mbar and flame sealed. Then the Pyrex tube was placed in an oven at 120 °C for 3 days. Wash three times with THF and DMF, collect the product by suction filtration, and dry the collected brick-red powder in vacuum overnight to obtain BTT-Bt-COF.

Abstract

The invention belongs to the field of material preparation, and provides a benzotrithiophene-benzothiazolyl covalent organic framework material, preparation thereof and application of the benzotrithiophene-benzothiazolyl covalent organic framework material in photocatalytic decomposition of water to produce oxygen. The benzotrithiophene-benzothiazolyl covalent organic framework material is prepared from benzotrithiophene trialdehyde (BTT) and 4, 4'-(benzo [C] [1, 2, 5] thiadiazole-4, 7-diyl) diphenylamine (Bt) through a Schiff base condensation reaction under a solvothermal condition, the responsiveness to visible light is enhanced, the utilization rate of solar energy is increased, oxygen is produced by photolysis of water, the cost is low, and safety and reliability are achieved. The covalent organic framework prepared by the invention has a large pi conjugated system and good chemical stability, is used for producing oxygen by photocatalytic decomposition of water, and has innovative significance. The material has a great application potential in the field of photocatalytic materials.

Description

technical field [0001] The invention belongs to the field of material preparation, and in particular relates to the preparation of a benzotrithiophene-benzothiazolyl covalent organic framework material and its application for photocatalytic decomposition of water to generate oxygen. Background technique [0002] With the rapid development of industry and the improvement of people's living standards, human beings are facing more and more energy demands, and the problem of energy shortage is becoming more and more severe. Facing this problem that currently plagues the world, there are generally two solutions. One is to open source, develop sustainable and clean energy as a substitute for fossil fuels, and at the same time increase the use of natural energy without polluting the environment. For example, solar energy is the most abundant energy in the ecosystem, and visible light accounts for 47%-50% of solar energy. The current society has very limited utilization of solar ene...
