Abstract

The invention discloses a preparation method of a bis(N-(4-carboxy)phenyl)peryleneimide zinc complex catalyst. In the method, zinc acetate, bis(N-(4-carboxy)phenyl)perylene Imide, triethylamine, water, and N,N'-dimethylimide are placed in a beaker for reaction. After the reaction is completed, filter and the filtrate evaporates slowly to obtain bis(N-(4-carboxy)phenyl)perylene Crystals of zinc imide complex catalysts. The method of the invention has the advantages of simple reaction process, high purity of the obtained product and simple aftertreatment. In the carbon dioxide cycloaddition reaction under atmospheric pressure, the conversion rate is as high as 97.5%, and the selectivity is as high as 97.9%.

Description

technical field [0001] The invention belongs to the technical field of catalyst material preparation, and relates to a preparation technology of bis(N-(4-carboxy)phenyl)peryleneimide zinc complex catalyst. [0002] technical background [0003] Metal-organic complexes are organic-inorganic hybrid materials with intramolecular pores formed by the self-assembly of organic ligands and metal ions or clusters through coordination bonds. Metal-organic complexes are rich in metal active sites, which determines their strong Lewis acidity and strong oxidative properties. Therefore, metal-organic complexes exhibit excellent catalytic properties in many organic catalytic reactions. It has been reported by a large number of literatures (Jiang, et al., Coord. Chem. Rev. 2018, 362, 1-23). At present, metal-organic complex catalytic synthesis chemistry has become one of the most promising research directions in the field of metal-organic framework science, and has attracted extensive atten...
