Abstract

The invention discloses a chiral porous organic polymer material and a preparation method, and belongs to the technical field of chemical and novel materials.The preparation method comprises the steps that a 3,3'-substitued binaphthol phosphate compound and / or an aromatic ring compound and / or a condensed ring compound and / or a heterocyclic ring compound are subjected to a Friedel-Crafts alkylation reaction at the temperature of 30 DEG C-120 DEG C under the action of a lewis acid catalyst in the presence of a formaldehyde dimethyl acetal cross-linking agent, and then the chiral porous organic polymer material with the specific surface area of 3-3000 m<2> / g.According to the chiral porous organic polymer material and the preparation method, by changing the components serving as reaction monomers, the specific surface area and pore parameters of the obtained chiral porous organic polymer material and the variety and content of binaphthol can be adjusted, and the product can be applied to the heterogeneous asymmetric catalyzing field by serving as a heterogeneous catalyst, has the advantages of being easy to operate, mild in reaction condition and the like, is low in cost of the raw materials and production cost and has the wide industrial application prospect.

Description

technical field [0001] The invention belongs to the technical field of chemistry and new materials, and in particular relates to a preparation method of a chiral porous organic polymer material. Background technique [0002] Compared with homogeneous catalysis, heterogeneous catalysis has been widely valued because it can conveniently realize the separation, recovery and reuse of products and catalysts. Heterogeneous catalysts are usually loaded on a certain carrier or the framework itself has a certain catalytic function. There are many types of supports used in heterogeneous catalysis, such as carbon supports, silicon supports, oxide supports, and organic polymer supports. These support materials have their own unique properties and are widely used in the field of heterogeneous catalysis. In recent years, with the development of material science, some new materials, such as graphene, carbon nanotubes, metal-organic framework materials and covalently bonded porous organic ...
