Summary: This study investigates two versions of reversed-phase/hydrophilic interaction mixed-mode core-shell stationary phases for high-performance liquid chromatography using porous organic polymers as the shell material. The researchers successfully obtained the SiO2@CHPCy-DB core-shell stationary phase by growing a porous shell on the surface of silica. The SiO2@CHPCy-DB exhibited reversed-phase/hydrophilic interaction mixed-mode with multiple retention mechanisms. Additionally, the role of the building blocks in porous organic polymers in regulating and improving separation was assessed by comparing the separation behavior of the homemade columns with a commercial column. The successful determination of trace analytes in complex samples using the SiO2@CHPCy-DB column demonstrates its potential.

Summary: This article presents a method to enhance the moisture resistance of fragile metal-organic frameworks (MOFs) by constructing a customized hydrophobic porous shell, NTU-COF, on MOF-5 using the Plug-Socket Anchoring strategy. It was found that the pore structure of MOF-5 was well preserved and could achieve complete CO2/N-2 separation even under humid conditions. Atomic resolution inspection of the interface between MOF-5 and NTU-COF revealed insights into the assembly mechanism of the core-shell structure.

Summary: An efficient hierarchical metal-organic framework (MOF), ZIF-8@Zn-MOF-74, with a core-shell structure and coordinately open/unsaturated metal sites (OMS), was successfully synthesized using a facile post-synthetic ligand exchange method. The core-shell structure consists of a SOD-type ZIF-8 core for molecular sieving and a Zn-MOF-74 shell with larger pore size for easier entrance and diffusion of gas molecules. The presence of OMS in the Zn-MOF-74 structure also contributes to a greater adsorption capacity. The prepared MOFs have a high BET surface area and total pore volume, making them promising for gas adsorption applications.
