Abstract

The invention relates to a polycarboxylic acid carbazole ligand-based indium-organic skeleton material and a preparation method thereof, and belongs to the technical field of crystalline materials. The chemical molecular formula is [(CH3)2NH2][InL].5H2O, wherein L is organic ligand 4,4',4'',4'''-(9H-carbazole-1,3,6,8-tetrasubstituted) para-benzoic acid radical. Organic ligand 4,4',4'',4'''-(9H-carbazole-1,3,6,8-tetrasubstituted) para-benzoic acid and indium nitrate are dissolved into a solution of N,N'-dimethylacetamide and tetrafluoroboric acid, and solvent thermal reaction is conducted to obtain the metal organic skeleton material. The metal organic skeleton material has a dye adsorption property and can be applied to industrial dye treatment.

Description

technical field [0001] The invention belongs to the technical field of crystalline materials, and the technology relates to metal-organic coordination self-assembly chemistry, in particular to a metal-organic framework material of indium (In) and a preparation method thereof. Background technique [0002] Since the first synthetic dyes came out in the 1850s, synthetic dyes have gradually replaced natural dyes. The rapid development of industries such as textiles, papermaking, printing and cosmetics has accelerated the large-scale production and use of synthetic dyes. According to incomplete statistics, the current annual consumption of textile dyes in the world is about 1.26 million tons, involving nearly 10,000 commodities in 15 categories. With the wide use of various dyes, about 10%-15% of the dyes are released into the environment during the preparation and use, because most of these dyes are extremely stable and difficult to be naturally degraded in the environment, ca...
