Abstract

The invention relates to a preparation method of a metallic organic macrocyclic crystalline-state material for splitting chiral amine. The method firstly comprises the following steps: firstly synthesizing a chiral ligand (1R,2R)-H2L, wherein the chiral ligand (1R,2R)-H2L is (1R,2R)-N-2-hydroxyl-3-tertbutyl-5-(4-pyridine)benzylene-N'-2-hydroxyl-3-tertbutyl-5-(4-pyridine)benzyl-cyclohexanediamine; then preparing the metallic organic macrocyclic crystalline-state material for splitting chiral amine by adopting a solvothermal method. Compared with the prior art, by adopting the solvothermal method, the preparation method is low in reaction temperature, short in reaction time, low-cost in reaction raw materials, and easy to prepare, as well as simple for synthesis operations, without the need of complicated aftertreatment, the prepared chiral metallic organic macrocyclic crystalline-state material is very stable in structure, strong in selective adsorption capability, and high in splitting efficiency.

Description

technical field

[0001] The invention belongs to the technical field of organic chemistry, and in particular relates to a method for preparing a metal-organic macrocyclic crystalline material used for splitting chiral amines. Background technique

[0002] In recent years, chiral metal-organic materials have shown broad application prospects in the fields of chiral recognition and separation, chiral fluorescence sensing, and heterogeneous asymmetric catalysis due to their variable topological structures. One of the hot research fields such as chiral materials science. It has been shown that framework materials with amphiphilic pores may exhibit strong interactions with those amphiphilic guest molecules, as long as the pore size and morphology of MOFs match those of the guest molecules. Materials can perform chiral recognition and separation of some chiral molecules. At present, the filling materials of chiral gas chromatographic columns used for the separation of chiral amin...
