Abstract:

Covalent organic framework materials (COFs) are a new type of crystalline porous materials, and their chiral materials have good application prospects in various fields. In this paper, TpBD(NH22 synthesized by the reaction of 1,3,5-trialdehyde phloroglucinol (Tp) and 3,3'-dinitrobenzidine (BD) was used as the covalent organic skeleton, and reacts with (1S)-(+)-10-camphorsulfonyl chloride (Cam) to prepare (1S)-(+)-10-camphorsulfonyl chloride derivative TpBD-1S-(+)-Cam. The derivative is a newly synthesized chiral covalent organic framework material. TpBD-1S-(+)-Cam was immobilized on silica gel to prepare a chiral column for high performance liquid chromatography to separate racemates. The experimental results show that the prepared COF, TpBD-1S-(+)-Cam, can separate warfarin, chlorpheniramine maleate, atenolol, metoprolol, zopiclone, 10-(9-anthryl)-2,2,2-trifluoroethanol, 1,2-benzophenone, ketoprofen, mexiletine hydrochloride, timolol 10 kinds of racemates and o,m,p-bromoaniline, o,m,p-iodoaniline are two kinds of positional isomers of benzene series. This material has potential as the stationary phase of high performance liquid chromatography.
