Embodiment 1

[0022] Embodiment 1 is composed of [Zn(mtz) 2 ] ∞ Preparation of Microporous Coordination Polymers

[0023] Add 50ml of 0.4mol / L Hmtz aqueous solution dropwise to 125ml of 0.08mol / L zinc-ammonia solution, remove part of the ammonia water under reduced pressure, and vacuum-dry the filtered white crystalline powder to obtain 1.72g of product, yield: 66% . The X-ray diffraction pattern of the product is shown in figure 2 .

Embodiment 2

[0024] Embodiment 2 is composed of [Zn(mtz) 2 ] ∞ Structural Characterization of Microporous Coordination Polymers

[0025] Single crystal X-ray diffraction data were collected on a Bruker Smart APEX CCD diffractometer, graphite monochromator, with Mo K. rays Data were collected as omega scans, and absorption correction was performed using the SADABS program. The direct method is used for analysis, and then the coordinates of all non-hydrogen atoms are obtained by the difference Fourier function method and the least square method, and finally the structure is corrected by the least square method. The organic hydrogen atoms of the compound are obtained by the theoretical hydrogenation method, and the hydrogen of the guest water molecule is found by the difference Fourier map. The calculation work is done on the PC using SHELXTL program. The detailed crystal determination data are shown in Table 1. structure see figure 1 .

Abstract

The invention discloses a sodalite porous coordination polymer material as well as a preparation method and application thereof. The sodalite porous coordination polymer material has a chemical formula of [Zn(mtz)2-x(mim)x] infinity (0<=x<2), wherein mtz is a deprotoned 3-methyl-1,2,4-triazole anion, and mim is a deprotoned 2-methylimidazole anion. The polymer material is crystallized in a cubic system and in an I-43m space group, the length of an alpha axis is 1.70 nm, the divalent zinc ion is quadridentate, mim is bidentate, and mtz is bidentate; and a nitrogen atom is not coordinated. The sodalite porous coordination polymer material has a sodalite three-dimensional coordination network structure and a cesium chloride three-dimensional pore canal with a pore ratio of 50%, and has good thermal stability and chemical stability; and the Langmuir specific surface is greater than 1800 m<2>/g, and various gases and vapor can be absorbed effectively. The sodalite porous coordination polymer material can be used for storing, separating, catalyzing and sensing materials, performing molecular recognition and heat exchange, and the like on materials by absorbing guest molecules.

Description

technical field [0001] The invention relates to the field of microporous coordination polymer porous materials, in particular to a sodalite type microporous coordination polymer material and its preparation method and application. Background technique [0002] Microporous coordination polymer is a new type of porous material developed in recent years. Compared with traditional porous materials such as molecular sieves and activated carbon, it has the advantages of low density, large specific surface area, strong chemical modifiability, and structural flexibility, and can be widely used in the fields of gas and liquid storage, separation, and heterogeneous catalysis. Examples of such microporous polymeric materials have been described in the following patents: US5862796, US7196210, US6930193, US7196210, US6624318 and US20080121105. [0003] However, most of the microporous polymer materials that have been developed so far are constructed by using multi-step organic reactions...
