Abstract

The invention discloses a 4-(1H-tetrazole-5-yl) zinc benzoate coordination polymer of a two-dimensional structure and a synthesis method and application thereof, relates to a metal-organic coordination polymer and a synthesis method and application thereof, and aims to provide a novel compound and a preparation method and application thereof. The molecular formula of the polymer is C12H13N5O3Zn. The method includes: firstly, dissolving cyanobenzoic acid, sodium azide and ammonium chloride into N, N-dimethylformamide, performing heating reflux prior to stirring reaction, subjecting a product obtained after reduced pressure distillation to acidifying with hydrochloric acid, and washing with deionized water to obtain a 4-(1H-tetrazole-5-yl) benzoic acid ligand; secondly, adding zinc sulfate and 4-(1H-tetrazole-5-yl) benzoic acid ligand into the mixed solution, performing stirring reaction to obtain a solution, transferring the obtained solution to a polytetrafluoroethylene-lined reaction kettle, performing temperature programming prior to reaction to obtain colorless tabular crystals, and filtering and drying to obtain the finished product. The 4-(1H-tetrazole-5-yl) zinc benzoate coordination polymer is applied to the field of fluorescence probes.

Description

technical field [0001] The invention relates to a metal organic coordination polymer and its synthesis method and application. Background technique [0002] Metal-organic coordination polymers are a kind of coordination compounds. Organic ligands coordinate with metal centers through covalent bonds to form substances with special structural and functional properties. Metal-organic coordination polymers can be synthesized by organic coordination. The selection and modification of metal-organic complexes can be tailored to the molecular or even atomic scale, so that their functional properties are extremely excellent. Therefore, more and more researchers have begun to conduct in-depth research on metal-organic complexes this year Systematic research. At present, metal-organic complexes have shown excellent performance in functional materials, biomedicine and other fields, especially in the fields of hydrogen storage, carbon dioxide adsorption and small molecule recognition, a...
