Journal of Separation Science, Год журнала: 2025, Номер 48(2)

Опубликована: Фев. 1, 2025

ABSTRACT Chiral covalent organic frameworks (CCOFs) are emerging porous materials with tunable chiral structures, abundant pores, and high surface areas, gaining significant attentions in separation, sensing, asymmetric catalysis. This review summarizes the synthesis methods of CCOFs their applications recognition. It discusses advantages limitations three strategies, including post‐modification, direct synthesis, chiral‐induced synthesis. The also highlights potential catalysis for efficient purification, detection, molecules. Challenges future directions preparation application addressed, aiming to guide further research practical applications.

ABSTRACT Covalent organic framework (COF) has been popularly utilized to prepare chromatographic stationary phases due its a great diversity of composition, unique structure, easy modification, and so forth. However, the irregular shape nanometer size scale most COF materials greatly hinders their direct utilization as column packing. Herein, poly (styrene‐divinylbenzene) loaded with p ‐phenylenediamine‐1,3,5‐triformylphloroglucinol nanoparticles that derived from ‐phenylenediamine 1,3,5‐triformylphloroglucinol microspheres are constructed by in situ growth method. Then, imine groups (styrene‐divinylbenzene)@ reduced amino followed quaternized. The characterized using SEM, Fourier transform infrared spectra, N 2 adsorption‐desorption experiment, According results, could perfectly combine possess good monodispersity functionality nanoparticles. customized exhibits separation properties for conventional anions, acids, carbohydrates.
