Embodiment 1

[0041] Synthesis of Ligand P-2COOH:

[0042] 1) Add 1.67g of tetrachloroperylene anhydride and 2.07g of 4-aminobenzoic acid into the reaction bottle, continue to add 30mL of propionic acid to make it evenly dispersed; feed nitrogen into the reaction bottle for 1 hour and react at 140°C for 48 hours; After the end, the reaction stock solution was precipitated with deionized water, and the precipitate was vacuum-dried to obtain the crude product P-2COOH as an orange-red powder.

[0043] 2) Add 2g of the powder generated in step 1) into the reaction bottle, add 50mL of dimethylformamide to make it evenly dispersed, heat at 140°C for 0.5h, stop heating, continue stirring for 2h, after the reaction is over, pump under reduced pressure The solvent was removed by filtration, and the precipitate was washed with 500 mL of a mixed solvent with a volume ratio of methanol and water of 1:1 to obtain purified P-2COOH (yield 80%), the structural formula of which was:

Abstract

The invention provides a three-dimensional perylene type metal-organic framework material capable of stabilizing anion radicals and a using method of the metal-organic framework material for light-thermal conversion. Perylene bisimide is simply modified and can be coordinated with metals. The method is excellent in universality and simple and convenient to operate. The prepared metal-organic framework is stable in structure, stable anion radicals can be produced by virtue of a photoinduced electron transfer process, and other compounding or later modification is not needed. The radical stabilizing method has the advantages of being simple, economic and environmental-friendly. The produced anion radicals have extremely high light-thermal conversion property of 53.8%, the light-thermal conversion property is higher than that of the vast majority of infrared light-thermal conversion materials, and the anion radicals are stable in near-infrared light-thermal conversion property and can berepeatedly used. Therefore, the three-dimensional perylene type metal-organic framework near-infrared light-thermal conversion material and the method for stabilizing the anion radicals provided by the invention have potential commercial application prospects.

Description

technical field [0001] The invention belongs to the technical field of metal organic framework materials, and in particular relates to a three-dimensional perylene metal organic framework material capable of stabilizing anion free radicals and its use method for photothermal conversion. Background technique [0002] Metal-organic frameworks, a class of stable porous crystal-like hybrid materials, have received increasing attention in recent years due to their wide range of properties and facile synthesis. Metal-organic frameworks with specific functions can be synthesized by selecting different ligands and metals. At the same time, MOFs can serve as stable cages to store "cargo." Peryleneimide anion radicals are widely used in the fields of photocatalysis, n-type semiconductors, and photoconductivity. Due to the specific near-infrared absorption of peryleneimide anion radicals, it also has potential application value in the field of near-infrared photothermal conversion. ...
