Problems solved by technology

However, the current solvothermal synthesis scheme is to mix metal inorganic salts, organic ligand powders, and solvents in proportion to directly carry out subsequent heating synthesis. Since the reaction system of high-temperature hydrothermal synthesis is relatively complicated and the reaction mechanism is not clear, the existing methods The synthesis efficiency is low, and the yield is usually between 40% and 80% through literature research

Abstract

The invention belongs to the field of function coordination polymer materials, and relates to a fluorescent coordination polymer material for adsorbing malachite green dye and a thermal synthesis method thereof. 1, 3-bis(4 '-carboxyl phenoxy) benzoic acid (called H3cpbda for short) and 1,2-bis(4-pyridine)-ethane (called bpa for short) are mainly used as organic ligand raw materials to react with metal cadmium salt and the like, and the novel coordination polymer material with fluorescence and dye adsorption performance is prepared through the improved step-by-step preprocessed solvent thermal synthesis method. The fluorescent coordination polymer material has the advantages of being high in synthesis yield, purity and crystal quality.

Description

technical field [0001] Based on the field of functional coordination polymer materials, the invention relates to a fluorescent coordination polymer material adsorbing malachite green dye and a thermal synthesis method thereof. Background technique [0002] As an inorganic-organic functional material, functional coordination polymers have shown attractive application prospects in gas adsorption, fluorescent materials, ion exchange, nonlinear optics, heterogeneous catalysis, molecular recognition, molecular magnets, etc. . Among them, fluorescent complexes can be used as potential fluorescent materials due to their fluorescent properties, while complex materials with dye adsorption properties are very rare, and have important application value for detecting adsorbed dye pollutants. [0003] The luminescent principle of coordination polymer light-emitting materials comes from the ligand itself, the metal itself and the ligand-metal correlation process. Its luminescent properti...
