Published: June 19, 2024

Synthesizing uniform functional covalent organic framework (COF) microspheres is the prerequisite of applying COFs as novel stationary phases for liquid chromatography. However, synthesis functionalized COF challenging due to difficulty in maintaining microspheric morphology when conferring functions. Here, a facile and universal "self-limited dynamic linker exchange" strategy developed achieve surface functionalization microspheres. Six different types are constructed, showing universality superiority strategy. The library microspheres' can be further enriched on demand by varying building blocks. attributed result delicate balance reaction thermodynamics molecular diffusion energy barrier. As demonstration, chiral used chromatography realized effective enantioseparation.

A series of tertiary amine suspended hyper-cross-linked ionic polymers (HCIPs), characterized by a rich mesoporous structure, high liquid (IL) density, and good CO2 adsorption capability, were readily prepared via postsynthetic method. The self-polymerization 1,3,5-tris(bromomethyl) benzene (TBB) or its copolymerization with 4,4'-bis(bromomethyl) biphenyl (BBP) in varying ratios, followed grafting N,N,N',N'-tetramethyl-1,3-propanediamine (TMPDA), yielded the target TMPDA-HCIPs. These HCIPs constitute one limited categories heterogeneous water-tolerant catalyst types ever developed for cycloaddition reaction between epoxides. Specifically, chloropropylene carbonate (CPC) was produced 99.9% yield 99% selectivity at 80 °C 1 bar pressure presence 22 mol % water relative to epoxide substrate. Furthermore, when simulated flue gas served as source, same ratio enhanced CPC from 81.9% 91.5% under MPa pressure, only slightly decreasing 94.1%. Additionally, could be easily recovered maintained catalytic performance after six cycles. In conclusion, this study presents robust efficient synthesis cyclic carbonates mild conditions, potentially reducing costs purifying real that contains vapor.
