Problems solved by technology

However, the former requires the synthesis of functional monomers with special structures, and the synthesis steps are cumbersome; the latter requires modifiable and reactive groups in the organic porous polymer, and the post-modification is usually unable to obtain a complete reaction due to the heterogeneous reaction. functional porous polymer
At the same time, most of the current organic porous materials are produced by the reaction of a single monomer or two monomers. The synthesized material has a single structure and function. To obtain a complex structure and multifunctional material, two or more steps may be required. , the reaction cycle is long and the reaction steps are complicated, and the separation of intermediates is also required, which is not conducive to modification and regulation

Description

technical field [0001] The invention relates to a functional organic porous polymer and its preparation method and application, belonging to the technical field of organic polymer materials. Background technique [0002] Organic porous polymers are a new class of porous materials that are connected by covalent bonds. They have attracted the attention of researchers because of their advantages such as diverse synthesis methods, adjustable structure, modifiable surface, and good stability. Gas adsorption, gas separation, sensors, catalysis, water treatment and other fields have broad application prospects. The functionality of organic porous materials is closely related to the application field. For example, the introduction of conjugated structures into covalent porous frameworks not only enables materials to be used in traditional fields such as gas storage, separation, and adsorption, but also has great applications in optical devices, chemical sensors, photocatalysis, sem...
