Abstract

The invention relates to a multifunctional biomimetic heterogeneous catalyst formed by an organic porous copolymer based on metalloporphyrin and a quaternary phosphonium salt, and a preparation methodthereof, wherein the metalloporphyrin and the quaternary phosphonium salt functional group are used as the main active component of the heterogeneous catalyst, the metalloporphyrin group is used as aLewis acid, the halogen ion in the quaternary phosphonium salt is used as a nucleophilic reagent, and the organic porous copolymer carrier containing metalloporphyrin and a quaternary phosphonium group is formed by carrying out co-polymerization on alkylene-functionalized metalloporphyrin and a quaternary phosphonium salt monomer. According to the present invention, the heterogeneous catalyst isused for the coupling reaction process of epoxy compounds and carbon dioxide, wherein the abundant N and P atoms in the polymer skeleton can increase the adsorption of CO2; and the porous organic polymer material can seal and limit the reaction substrate in the nano-scale pores and increase the concentration of the substrate at the catalytic site, such that the catalyst has double advantages of extremely high activity and extremely high stability.

Description

technical field

[0001] The field of the invention belongs to the field of heterogeneous catalysis, and specifically relates to a multifunctional biomimetic heterogeneous catalyst containing metal porphyrin and quaternary phosphonium salt copolymer used in the coupling reaction of carbon dioxide and epoxy compounds and a preparation method thereof. Background technique

[0002] The design and synthesis of porous organic polymer materials has gradually become one of the new hotspots in the field of porous materials research. Compared with traditional inorganic microporous materials and metal-organic frameworks (MOFs), the framework of organic microporous polymers is composed of pure organic molecules, which are connected to each other by covalent bonds, and have open channels and excellent pore properties. . More importantly, due to the diversity of organic chemical synthesis methods, it provides a wealth of synthetic routes and construction methods for the construction of or...
