Quickly synthesized COFs (Covalent Organic Frameworks) material and application thereof to detection of water content in organic solvent

The invention discloses a rapidly synthesized COFs (covalent organic frameworks) material and application of the rapidly synthesized COFs material to detection of water content in an organic solvent, and belongs to the fields of covalent organic framework materials and analysis and detection. According to the method, 1, 3, 5-tri (4-aminophenyl) benzene and 2, 5-dimethoxybenzene-1, 4-dicarboxaldehyde are taken as raw materials, TAPB-DMTP-COF is rapidly synthesized by adopting a grinding method, and the specific steps are as follows: p-toluenesulfonic acid and 1, 3, 5-tri (4-aminophenyl) benzene are fully mixed; then adding 2, 5-dimethoxybenzene-1, 4-dicarboxaldehyde, fully grinding, and heating; soaking the obtained dark red powder in hot water, filtering and collecting a primary product; respectively washing with tetrahydrofuran and acetone for 3 times, and then centrifugally washing with absolute ethyl alcohol for 5 times; the method comprises the following steps: adding DMTP-COF into a reaction kettle, stir
