Abstract

The invention discloses a preparation method and application method of a benzothiadiazole-based large-aperture MOF material. The method comprises the following steps: respectively dissolving a certainamount of metal salts and ligands in a solvent to obtain a solution A and a solution B; fully mixing the solution B and the solution A, heating and keeping the temperature until the reaction is finished, and cooling to room temperature to obtain a crystal; and washing the crystal with eluent and drying to obtain an MOF material. The method comprises the steps of material proportioning and mixing,grinding, cooling, purifying and the like. The preparation method mainly comprises the steps: respectively dissolving zirconium salt, zinc salt, aluminum salt and other metal salts and ligands in N,N-dimethylformamide, uniformly mixing, heating to 120 DEG C in vacuum, keeping the temperature for about 24-72 hours, finally cooling to room temperature at a certain cooling rate, centrifuging, filtering, washing and drying to obtain the crystal. The preparation method disclosed by the invention has the advantages of low cost, simple preparation process, suitability for batch production and the like.

Description

technical field [0001] The present invention relates to the field of preparation and application of chemical materials, in particular to a preparation and application method of a large-aperture MOF material based on benzothiadiazole. Background technique: [0002] Amines and their derivatives play an important role in food, dyes and medicines. In recent years, incidents of unqualified amine content in food, textiles and other fields have frequently attracted attention. Therefore, how to quickly, sensitively and efficiently detect amines has become the research direction of many scientists. However, the current detection methods for amines are mainly liquid chromatography, electrochemical detection, etc., but these detection methods have the disadvantages of long time consumption and high energy consumption, so it is necessary to develop a detection method with fast reaction speed, high sensitivity and low detection limit . Metal-organic frameworks (MOFs) are crystalline ma...
