In this study, four novel 2D chiral CMOFs were successfully synthesized and demonstrated their potential applications in dye adsorption, degradation, and chiral separation.
Covalent metal-organic frameworks (CMOFs) are a novel class of porous materials made by combining the chemistry of metal- and covalent organic frameworks (MOFs and COFs) and have attracted sustained attention, yet the preparation of chiral CMOFs remains a challenge. Herein, four novel 2D chiral CMOFs have been prepared through imine condensation between enantiopure BINOL-based dialdehyde linkers and copper(i) cyclic trinuclear units (Cu-CTUs). The synthesized 2D chiral CMOFs ((R)/(S)-JNM-10 and (R)/(S)-JNM-11) afford highly crystalline, well-ordered porous structures, good thermal stability and chemical robustness. JNM-10 and JNM-11 can be used for dye adsorption and degradation and the chiral separation of amino acids like tryptophan. This work not only provides a promising platform for the synthesis of chiral CMOFs but also motivates further research on the enantioselective recognition of chiral molecules.
