Problems solved by technology
[0003] However, there are still many key issues to be solved before the practical application of organic porous polymers, such as: the processing of organic porous materials into membranes
Most organic porous polymers are applied in the form of thin films, and organic porous polymers are polymer compounds with a high degree of crosslinking. The preparation process is a rapid crosslinking process, which leads to insoluble organic porous polymers after reaction. , Infusible powder form, which makes it difficult to process organic porous polymers into films, which limits the practical application of organic porous polymers

Description
technical field [0001] The invention relates to the technical field of organic synthesis, in particular to a nitrogen-containing heterocyclic compound and a soluble porous polymer. Background technique [0002] Organic porous polymers are porous polymers formed by covalently linking organic units, and a network framework structure with permanent pores can be obtained by designing functional organic units and controlling the polymerization reaction. Compared with classical porous materials (such as molecular sieves, mesoporous silicon, etc.), the biggest advantage of organic porous polymers is that they can use the rich diversity of organic building units and synthetic reactions to precisely control the properties of organic porous polymers at the atomic scale. The organic porous framework structure with specific structure and specific function can be obtained through pore size, specific surface area and pore environment. With the enrichment of synthesis reactions and the co...
