Pyrrolidinyl covalent organic framework material as well as preparation method and application thereof

The invention belongs to the technical field of catalyst preparation, and particularly relates to a pyrrolidinyl covalent organic framework material as well as a preparation method and application thereof. A preparation method of the catalyst COF-LA comprises the following steps: uniformly mixing a monomer L-A, 4-[3, 5-bis (4-formylphenyl) phenyl] benzaldehyde and a solvent, adding acetic acid, uniformly mixing to obtain a mixed solution, carrying out a heating reaction on the mixed solution, cooling to room temperature, cleaning to obtain a precipitate, and drying to obtain the COF-LA. The catalyst can effectively catalyze Claisen-Schmidt reaction, high temperature is not needed, the dosage of the catalyst is small, and catalysis can be achieved without other additives. Meanwhile, the catalyst can be recycled and is easy to recover, the utilization rate of the catalyst is increased, the cost is reduced, and industrial popularization and application are facilitated. 本发明属于催化剂制备技术领域，具体涉及一种吡咯烷基共价有机框架材料及其制备方法与应用。
