Abstract

The invention relates to a monocrystal structure of a luminescent material of a cadmium coordination compound with blue light performance, blue light performance and a preparation method thereof. The molecular formula of a product provided the invention is CdC10H5N3O4. The molecular weight of the product is 343.57, and the product belongs to a single orthorhombic system. An orange bulk crystal is synthesized by a hydrothermal method. The preparation method provided by the invention is as follows: respectively dissolving cadmium chloride and 2-pyridyl-1H- imidazole-4, 5-dicarboxylic acid in an aqueous solution, and then, adding a small amount of pyrazole, adjusting the pH value through an HCl solution, putting the solution in a stainless steel kettle sleeve, and burning the stainless steel kettle sleeve in an oven of 150 DEG C for three and a half days to obtain an aurantiacus bulk crystal. The product prepared by the method provided by the invention is a monocrystal with an intact crystal form; and the prepared compound is clear in composition and structure, as shown in a luminous performance test, the monocrystal structure provided by the invention exhibits blue fluorescence and has high thermal stability. The yield of the product prepared by the method provided by the invention is high and can reach 45%.

Description

technical field [0001] The present invention relates to a single crystal structure of a metal organic luminescent material and a preparation method thereof, and relates to a synthesis of a cadmium coordination compound with a three-dimensional structure, more specifically [Cd(2-pyridyl-1H-imidazole-4, 5-dicarboxylic acid)] n The single crystal structure of the complex and its preparation method. Background technique [0002] In recent years, because metal-organic frameworks not only have diverse structures, but also have potential applications in catalysis, optics, magnetism, ion exchange, etc., their design and synthesis have attracted widespread attention and become a research hotspot. A feasible approach to synthesize structurally novel metal-organic complexes is to select multidentate organic ligands that can coordinate to multiple metals. Using organic ligands containing both nitrogen and oxygen, such as 3,4-pyridinedioic acid, 4,5-imidazoledioic acid, etc., metal-org...
