Embodiment 1

[0033] Embodiment 1: with 0.021mmol BIm and 0.021 mmol Zn (NO 3 ) 2 ·6H 2 O was dissolved in 2.0 mL of DMF solvent, and added to a hard glass tube with one end closed, followed by heating, melting and sealing. Put the closed glass tube into an oven and heat it at a constant temperature of 100 degrees Celsius for 24 hours, collect crystals, wash with DMF, and dry to obtain the target product, yield: 50%.

Embodiment 2

[0034] Embodiment 2: 1.94 mmol BIm and 1.94 mmol Zn(NO 3 ) 2 ·6H 2 O was dissolved in 90 mL DMF solvent, divided into 10 small glass bottles, each 9.0 mL, and then placed in a wide-mouthed triethylamine / n-hexane mixed solvent (73 mL, volume ratio 3 / 70) bottle (500 mL), slow diffusion for 3 days to obtain the product. Washing with DMF, drying to obtain the target product, yield: 90%.

Embodiment 3

[0035] Embodiment 3: with 0.021mmol BIm and 0.021mmol Cu(NO 3 ) 2 ·3H 2 O was dissolved in 2.0 mL DMF / ethanol (volume ratio, 4:1) solvent, and added to a hard glass tube with one end closed, followed by heating, melting and sealing. Put the closed glass tube into an oven and heat it at a constant temperature of 100 degrees Celsius for 24 hours, collect crystals, wash with DMF, and dry to obtain the target product, yield: 60%.

Abstract

The invention discloses an akin molecular sieve metal double imidazoles porous coordination polymer, a preparation method thereof and application thereof. The akin molecular sieve metal double imidazoles porous coordination polymer in the invention is a compound represented by the following chemical formula: {[M(BIm)]XxDMFXyC2H6OXzH2O}, wherein M=Zn, x=0.9, y=0, z=0; M=Cu, x=1.2, y=0, z=0; M=Mn, x=0.2, y=0, z=0; M=Ni, x=0.4, y=1.2, z=1.0, BIm is double-4-imidazoles methylene diamine, DMF is N, N-dimethyl formamide and H2O is water. The compound is prepared through a solvothermal method or slow diffusion method, and an obtained crystal has high purity. The coordination polymer of the present invention has good heat stability and extreme adsorption performance to CO2 at zero DEG C and normal pressure. Thus the coordination polymer can be used as an adsorption material in application.

Description

technical field [0001] The invention belongs to the technical field of transition metal complex materials, and relates to microporous metal-organic coordination polymer materials, in particular to a new type of molecular sieve-like metal bisimidazole porous coordination polymer and its preparation method and application, belonging to microporous coordination polymerization The material is a three-dimensional molecular sieve-like coordination polymer with micropores and a CO 2 Has a high adsorption capacity. Background technique [0002] Molecular sieves are widely used in the fields of petrochemical, fine chemical and medicinal chemistry because of their catalytic, adsorption and separation properties. In recent years, molecular sieve-like metal imidazole porous coordination polymers have aroused great interest, not only because of their network structure of molecular sieves, but also because of their extreme stability and potential applications in catalysis, separation, ga...
