Embodiment 1

[0046] First, 0.25 millimoles (mmol) of Al(NO 3 ) 3 9H 2 O, 0.25 mmol of 4,4'-diphenyl ether dicarboxylic acid (H 2 OBA) and 6.0 milliliters (mL) of N,N-dimethylformamide (DMF) into a Teflon inner cup. Then, put the Teflon inner cup in an iron cup, and put the iron cup into a high temperature furnace. In the high temperature furnace, the temperature was raised to 120° C. at a heating rate of 60° C. / hr. Then, the reaction was carried out at a reaction temperature of 120° C. for 2 days. After the reaction was completed, it was cooled down to room temperature at a cooling rate of 6°C / hr. Finally, suction filtration was performed, and the product was washed with ethanol and water. After drying, the product Compound 1 was obtained as a white powder.

[0047] The crystal system of compound 1 is tetragonal, and the space group is I4 1 / a. see Figure 2A to Figure 2D , Figure 2A It is a schematic diagram of the coordination environment of 4,4′-diphenyl ether dicarboxylic a...

Embodiment 2

[0053] First, 0.5 millimoles (mmol) of Al(NO 3 ) 3 9H 2 O, 0.5 mmol of 4,4'-stilbene dicarboxylic acid (H 2 SDA) and 10.0 milliliters (mL) of N,N-diethylformamide (DEF) into a Teflon inner cup. Then, put the Teflon inner cup in an iron cup, and put the iron cup into a high temperature furnace. In the high-temperature furnace, the temperature was raised to 180° C. at a heating rate of 60° C. / hr. Then, reaction was carried out at a reaction temperature of 180° C. for 1 day. After the reaction was completed, it was cooled down to room temperature at a cooling rate of 6°C / hr. Finally, suction filtration was performed, and the product was washed with ethanol and water. After drying, the milky white powder of product compound 2 can be obtained.

[0054] The crystal system of Compound 2 is orthorhombic, and the space group is Imma. see Figure 6A to Figure 6D , Figure 6A It is a schematic diagram of the coordination environment of 4,4'-stilbene dicarboxylic acid disclosed ...

Abstract

The invention provides a metal-organic framework material, a preparing method thereof and uses of the material. The chemical formula of the material is M(OH)(L), wherein the M is a trivalent aluminum ion, and the L is a bidentate of 4,4'-oxybisbenzoic acid, or 4,4'-stilbenedicarboxylic acid. The preparing method includes blending a trivalent aluminum salt and the bidentate to form a solution, and heating the solution to prepare the material. The material can be used for absorbing gas.

Description

technical field [0001] The present invention relates to a metal organic framework material, its preparation method and its use, especially a metal organic framework material with trivalent aluminum ions and double bud ligands, its preparation method and its use. Background technique [0002] Metal-organic frameworks (MOFs) are organic-inorganic coordination polymers that have developed rapidly in recent years. Generally speaking, metal-organic framework materials are bonded by central metals and organic ligands. Moreover, according to the stacking mode of the central metal and organic ligands in the metal-organic framework, the metal-organic framework can be further classified into one-dimensional, two-dimensional and three-dimensional arrangements. [0003] Metal-organic frameworks are porous materials. In general, porous materials are often used in the fields of gas adsorption, gas separation, catalysis, and sensing elements due to their large number of pores and large s...
