Abstract

The invention discloses a Zn-MOF material with cation sensing performance and a preparation method. The chemical formula of Zn-MOF material is Zn(H 2 O) 2 (C 8 h 4 o 4 ) 1 / 2 (C 5 h 3 N 2 o 2 ), the molecular formula is C 9 h 9 N 2 o 6 Zn, with a molecular weight of 306.58, belongs to the orthorhombic crystal system, Pbca space group. Weigh ZnCl 2 Dissolve in distilled water and stir; dissolve 2-pyrazinecarboxylic acid, terephthalic acid and KOH in N,N-dimethylformamide solution and stir. The two were then mixed, stirred, and transferred to a stainless steel reaction kettle lined with polytetrafluoroethylene. React at 80°C for five days. Cool down to room temperature by program to obtain colorless blocky crystals. Collect, wash, and vacuum-dry to obtain the target product. The method of the invention has the advantages of simple operation, mild conditions and high yield, and the prepared Zn-MOF material has good cation sensing performance.

Description

technical field [0001] The invention relates to the field of coordination polymers, in particular to a Zn-MOF material with cationic sensing performance and a preparation method. Background technique [0002] In recent years, significant progress has been made in the design and construction of metal-organic framework compounds (Metal-Organic Framework, MOF). Scientists have obtained a large number of new materials with different topological structures through continuous efforts. In this field, there is strong interest in the fact that MOF materials can not only exhibit novel aesthetic structural diversity, but also that these compounds have extremely important potential applications in various aspects such as optics, electricity, magnetism, catalysis, and gas adsorption. It is noteworthy that the exploration of MOF materials in sensing is usually used to detect cations, anions, small molecules, water vapor, explosives, etc., and they show good sensitivity and high selectivit...
