Embodiment 1

[0020] The organic ligand H 3 CTTA (0.01 mmol), and In(NO 3 ) 2 ·6H 2 O (0.04 mmol) was mixed evenly in 2.0 mL of N,N-dimethylformamide, 0.025 mL of nitric acid (concentration: 7M) and 0.4 mL of deionized water were added, and sealed in a 4 mL glass vial. Crystals of the metal-organic framework were obtained via thermal reaction at 120°C for 24 hours.

Embodiment 2

[0022] The organic ligand H 3 CTTA (0.01 mmol), and In(NO 3 ) 2 ·6H 2 O (0.04 mmol) was mixed evenly in 2.0 mL of N,N-dimethylformamide, 0.025 mL of nitric acid (concentration: 7M) and 0.3 mL of deionized water were added, and sealed in a 4 mL glass vial. Crystals of the metal-organic framework were obtained via thermal reaction at 100°C for 48 hours.

[0023] The test result of the product of above-mentioned embodiment gained is identical, specifically sees following:

[0024] (1) Determination of crystal structure:

[0025] A single crystal with a suitable size was selected under a microscope, and the data was collected using an Agilent Technologies SuperNova single crystal diffractometer at 100K. Data collection using Cu-Kα monochromated by graphite monochromator target ray. CrysAlisPro software was used for data collection and restoration. The crystal structure was solved by direct method using SHELXTL-97 program. The coordinates of all non-hydrogen atoms were de...

Abstract

A metal-organic framework material based on tricarboxylic acid ligand In, a preparation method and application thereof, belonging to the technical field of crystalline materials. The chemical formula is [In 3 (OH) 3 (CTTA) 2 ], H 3 CTTA is 5′-(4-carboxyphenyl)-2′,4′,6′-trimethyl-[1,1′:3′,1″-terphenyl]-4,4″-dicarboxylic acid . The metal-organic framework was synthesized under closed conditions, the organic ligand 5′-(4-carboxyphenyl)-2′,4′,6′-trimethyl-[1,1′:3′,1″ ‑terphenyl]‑4,4″‑dicarboxylic acid (H 3 CTTA) and indium nitrate in N,N-dimethylformamide, through the solvothermal reaction to obtain metal organic framework material crystals; this metal organic framework material exhibits rare water stability of In MOFs, and shows Fe 3+ Selective quenching.

Description

technical field [0001] The invention belongs to the technical field of crystalline materials, and the technology relates to a metal-organic coordination polymer material, and is characterized in that it is an In metal-organic framework material, a preparation method and an application thereof. Background technique [0002] With the development of science and technology, it has promoted the development of social economy and improved people's living standards, but human beings have also paid a huge price. With the development of industry, many metal ions such as lead, mercury, cadmium, cobalt, etc. enter the atmosphere, water, and soil, causing serious environmental pollution. The benefit or harm of metals in water depends not only on the type and physical and chemical properties of the metal, but also on the concentration, valence and form of the metal. Even if the concentration of beneficial metal elements exceeds a certain value, it will have severe toxicity, making animals...
