Abstract

The invention discloses a manganese-based luminescent metal organic framework material as well as a preparation method and application thereof. The manganese-based luminescent metal organic frameworkmaterial has a chemical formula of {[Mn(Tipe)4(bcpf)2](DMF)}n. The preparation method comprises the following steps: mixing manganese chloride tetrahydrate, 1,1,2,2-tetra[4-(imidazole-1-yl)phenyl]ethylene and 4,4'-sulfonyl dibenzoic acid according to a ratio, adding N,N-dimethyl formamide and water of a certain volume ratio, mixing and stirring to be filled in a glass bottle, reacting in a constant temperature drying oven at the temperature of 80-100 DEG C for 2-3 days, so as to obtain the colorless product, namely the luminescent metal organic framework material. The luminescent metal organicframework material {[Mn(Tipe)4(bcpf)2](DMF)}n disclosed by the invention can achieve potential application in the detection of a sensor material containing micro water content in the methanol solvent, and has excellent selectivity and high sensitivity.

Description

technical field [0001] The invention belongs to the field of luminescent metal organic framework materials, and in particular relates to a manganese-based luminescent metal organic framework material and its preparation method and application. Background technique [0002] Metal–organic frameworks (MOFs), also known as coordination polymers, are a class of crystalline materials with one-dimensional, two-dimensional, and three-dimensional infinite network structures formed by self-assembly of organic ligands and metal centers. . It has both the rigidity of inorganic materials and the flexibility of organic materials. It presents great development potential and attractive development prospects in modern materials research. [0003] Methanol is volatile, and the gas has toxic reactions to respiratory mucosa and eyesight. Methanol is highly toxic and has the greatest impact on the nervous system and blood system of the human body. It will produce toxic reactions if it is inge...
