Abstract

The invention discloses an organic-inorganic hybrid polyoxomolybdate crystal material and a preparation method thereof. The organic-inorganic hybrid polyoxomolybdate crystal material comprises a polyoxomolybdate crystal, and the chemical formula of the polyoxomolybdate crystal is [Ni(H2O)(C12H8N2)2]2(PMo12O40(VO)2].2H2O, the polyoxomolybdate crystal belongs to a triclinic system, and the space group of the polyoxomolybdate crystal is P-1. The organic-inorganic hybrid polyoxomolybdate crystal material is prepared by adopting a hydrothermal synthesis method. The preparation method of the organic-inorganic hybrid polyoxomolybdate crystal material comprises the following steps: and stirring and mixing molybdenum oxide, ammonium metavanadate, 1, 10-phenanthroline, nickel acetate, phosphoric acid and water, and then putting the mixture in a closed container, reacting for at least 1 hour at least 160 DEG C, and carrying out solid-liquid separation, thus obtaining the organic-inorganic hybrid polyoxomolybdate crystal material. When being excited by ultraviolet light with the wavelength of 310nm, the organic-inorganic hybrid polyoxomolybdate crystal material emits relatively strong fluorescence at a place with the central wavelength of 410nm, which shows that the crystal material has good fluorescence characteristic.

Description

technical field [0001] The invention belongs to the field of organic-inorganic hybrid materials and complex crystal materials, in particular to an organic-inorganic hybrid polymolybdate crystal material and a preparation method thereof. Background technique [0002] Early transition metal atoms (vanadium, niobium, tantalum, molybdenum, and tungsten) can form multi-metal-oxygen clusters in their high oxidation states. Due to their unique molecular and electronic structures, these substances often have excellent electrical conductivity and magnetic properties. , redox, catalytic and optical nonlinear properties, and has a wide range of applications in analysis, clinical diagnosis, catalysis (including photocatalysis), biochemistry, medicine and material science. [0003] With the development of advanced materials, the assembly of supramolecular polyoxometallates with specific compositions and functions has attracted more and more attention. With the development of inorganic p...
