Asymmetric catalytic synthesis of chiral covalent organic framework composite (S)-DTP-COF@SiO for HPLC enantioseparations by normal-phase and reversed-phase chromatographic modes.

A novel CCOF core-shell composite material (S)-DTP-COF@SiO was prepared via asymmetric catalytic and in situ growth strategy. The prepared (S)-DTP-COF@SiO was utilized as separation medium for HPLC enantioseparation using normal-phase and reversed-phase chromatographic modes, which displays excellent chiral separation performance for alcohols, esters, ketones, and epoxides, etc. Compared with chiral commercial chromatographic columns (Chiralpak AD-H and Chiralcel OD-H columns) and some previously reported chiral CCOF@SiO (CC-MP CCTF@SiO and MDI-β-CD-modified COF@SiO)-packed columns, there are 4, 3, 13, and 15 tested racemic compounds that could not be resolved on the Chiralpak AD-H column, Chiralcel OD-H column, CC-MP CCTF@SiO column, and MDI-β-CD-modified COF@SiO column, respectively, which indicates that the resolution effect of (S)-DTP-COF@SiO-packed column can be complementary to the other ones.

Chiral Covalent-Organic Framework MDI-β-CD-Modified COF@SiO Core-Shell Composite for HPLC Enantioseparation.

The chiral covalent-organic framework (CCOF) is a new kind of chiral porous material, which has been broadly applied in many fields owing to its high porosity, regular pores, and structural adjustability. However, conventional CCOF particles have the characteristics of irregular morphology and inhomogeneous particle size distribution, which lead to difficulties in fabricating chromatographic columns and high column backpressure when the pure CCOFs particles are directly used as the HPLC stationary phases. Herein, we used an in situ growth strategy to prepare core-shell composite by immobilizing MDI-β-CD-modified COF on the surface of SiO-NH.
