Preparation method and application of cadmium-based metal organic framework Cd-MOF material

Abstract

The invention provides a preparation method and application of a cadmium-based metal organic framework Cd-MOF material. The preparation method is characterized by comprising the following steps: step1, dissolving cadmium nitrate in water, dissolving a ligand 5-(bis(4-carboxylbenzyl)amino isophthalic acid in N,N-diethylformamide, and mixing the ligand 5-(bis(4-carboxylbenzyl)amino isophthalic acidand N,N-diethylformamide with ethanol; step 2, pouring the mixed solution into a polytetrafluoroethylene reaction kettle lining, and carrying out ultrasonic treatment; step 3, putting the reaction kettle into a blast drying oven for heating; and step 4, cooling the reaction kettle to room temperature, and filtering the reaction solution to obtain the yellow petal-shaped Cd-MOF crystal. The synthesis method of the Cd-MOF fluorescent material is simple, the yield and the purity are high, the accurate structure of MOF can be analyzed through single crystal diffraction, and the Cd-MOF fluorescentmaterial synthesized by the method has the characteristics of simple operation, less time consumption and low cost when alpha,beta-unsaturated aldehyde and saturated aldehyde are distinguished and detected.

Description

technical field [0001] The invention belongs to the technical field of preparation of fluorescent sensing materials, and in particular relates to a preparation method and application of a cadmium-based metal organic framework Cd-MOF material. Background technique [0002] α, β-unsaturated aldehydes are an important class of chemical raw material intermediates, and one of the more important applications is the preparation of allyl alcohols through selective reduction and hydrogenation of C=O bonds, such as α-phenylethyl alcohol and cinnamyl alcohol It is mostly used in the synthesis of aroma blending agents, food flavor additives and pharmaceutical intermediates, etc., and has high economic value. However, the by-products in the catalytic process will seriously affect the conversion rate of the catalytic reaction and the purity of the product, so the determination of the content and type of by-products is very important. At present, the commonly used methods for determining ...
