Abstract

The invention belongs to the technical field of catalyst preparation and particularly relates to a chiral catalyst (S)-DTP-COF and a preparation method and application thereof. The preparation methodof the chiral catalyst (S)-DTP-COF comprises the steps of: putting cuprous triflate and (S,S)-2,6-bis(4-phenyl-2-oxazolyl-2-yl)pyridine into a round-bottom flask, taking chloroform as a solvent, and carrying out stirring and dissolving; adding 2,5-dimethoxyterephthalaldehyde, 1,3,5-tris(4-aminophenyl)benzene and phenylacetylene into the round-bottom flask and stirring at room temperature for 48 hours; and finally adding an acetic acid and carrying out stirring for 24-48 hours to obtain (S)-DTP-COF. The catalyst can effectively catalyze Michael addition reaction, high temperature is not needed,the amount of the catalyst is small, no other additives are used, and heterogeneous catalysis can be achieved. Meanwhile, the catalyst can be reused and easily recycled, so that the utilization rateof the catalyst is improved, the cost is reduced and industrial popularization and application are facilitated.
