Embodiment 1

[0025] Weigh 0.03 mmol (9.36 mg) of tetrafluorobiphthalic acid, 0.03 mmol (15 mg) of thorium nitrate and 2.56 mmol (160 μl) of concentrated nitric acid and add it to a mixed solvent of 2 ml of DMF and 0.5 ml of water , fully mixed to obtain a colorless and transparent solution; then transferred to a polytetrafluoroethylene-lined autoclave with a volume of 20 ml, and reacted at a constant temperature of 358~373 K for 6 hours to obtain colorless octahedral crystals, that is, thorium coordination polymer [Th 6 O 4 (OH) 4 (C 14 H 4 F 4 O 4 ) 6 (H 2 O) 6 ], (C 14 H 4 F 4 O 4 is the molecular formula of 3,3',5,5'-tetrafluorobiphenyl-4,4'-dicarboxylic acid to remove two carboxyl protons).

Abstract

The invention provides a thorium coordination polymer, its preparation method and its application in propyne storage. The chemical formula of the thorium coordination polymer is [Th 6 o 4 (OH) 4 (C 14 h 4 f 4 o 4 ) 6 (H 2 O) 6 ], C 14 h 4 f 4 o 4 It is the molecular formula of 3,3',5,5'-tetrafluorobiphenyl-4,4'-dicarboxylic acid with two carboxyl protons removed. It belongs to the cubic crystal system and the space group is Fm‑ 3m ; the unit cell parameter is a =28~28.1 Angstroms, b =28~28.1 Angstroms, c =28~28.1 Angstroms, =90º, =90º, =90º, Z =4. The preparation method of the thorium coordination polymer comprises the following steps: mixing thorium salt, 3,3',5,5'-tetrafluorobiphenyl-4,4'-dicarboxylic acid, nitric acid and solvent, and then transferring to a reaction kettle , and then react under the condition of 358~373 K to obtain the thorium coordination polymer. The thorium coordination polymer can be used to store propyne gas.

Description

technical field [0001] The invention belongs to the field of coordination chemistry, and in particular relates to a thorium coordination polymer, a preparation method of the thorium coordination polymer and the application of the thorium coordination polymer in propyne storage. Background technique [0002] Metal-Organic Framework (MOF), also known as porous coordination polymer, is a new type of porous crystalline solid material formed by organic ligands bridging inorganic metal ions or metal clusters through coordination bonds. [0003] Many common substances, such as carbon materials and zeolitic materials, are porous materials that have long been used as adsorbents. To better handle gases, there is an urgent need to develop porous materials with large storage capacity and high separation efficiency, especially those with high porosity and good modularity of different sizes. In this context, many novel porous adsorbents, such as metal-organic frameworks (MOFs), covalent ...
