The invention belongs to the field of organic deacidification materials, and particularly relates to a Tailing structure covalent organic framework membrane material and application thereof. The invention provides a Tailing structure covalent organic framework membrane material, which is characterized in that an organic-organic solvent interface method is adopted, 2, 4, 6-trihydroxy-1, 3, 5-benzenetricarboxaldehyde is taken as a node monomer, and the node monomer and m-phenylenediamine are subjected to an aldehyde-amine condensation reaction to synthesize the Tailing structure covalent organic framework (t-TpMa-COF) membrane material. The t-TpMa-COF material provided by the invention has good thermal stability and acid-base stability, and efficient deacidification treatment of high-acidity feed liquid can be effectively realized. The invention provides a new thought for the design and preparation of a novel Turing structure membrane material, and also provides a new solution for deacidification, volume reduct
