Porous metal–organic frameworks based on 3,6-bis(4-benzoic acid)-N-(4-benzoic acid)carbazole for HPLC separation of small organic molecules

Abstract

A stable porous MOF with a controllable particle size can be used as an HPLC situational phase for small organic molecule separations.

Dynamic Pendulum Effect of an Exceptionally Flexible Pillared‐Layer Metal‐Organic Framework†

“…To the best of our knowledge, this is the first observation of the guest‐induced conformation inversion for both the rhombic grids and pillars of MOFs, and the inversion of rhombic grids and pillars is independent. [ 14‐20 ]…”

“…Porous coordination polymers (PCPs) or metal–organic frameworks (MOFs) are attractive for their high crystallinity, structural diversity and modular designability, [ 9‐11 ] and great efforts have been devoted to the design, preparation and application of MOFs. [ 12‐27 ] Thanks to the assembly via relatively weak and sensitive coordination bonds, a few MOFs exhibit distinctive framework flexibilities and stimuli‐responsive performances including breathing behaviors, gate opening transformations, hysteresis and multi‐ step sorption behaviors, even shape‐memory effect. [ 28‐32 ] Such structural transformations of flexible MOFs induced by external physical or chemical stimuli indicate a great potential application in the field of artificial molecular machines, whose long‐range order can help to bridge the gap between complex motions on molecular level and the responsive behaviors of the macroscopic solid materials.…”

(Keynote) Electromagnetic Field Stimulated MOFs

“…Among metal-organic frameworks (MOFs), build up from metal-nodes and organic linker molecules, lanthanide-based MOFs have attracted great attention due to their fascinating characteristic coordination and unique optical properties arising from 4f electrons (1)(2)(3). The narrow bandwidth fluorescence of the lanthanides metal nodes and the wide absorption of the chromophores in the linker, which act as antennae to excite the shielded f-orbitals of lanthanides metal-nodes, contributed to the numerous applications in luminescent sensors (4), light-emitting devices (5) and anticounterfeiting barcodes (6).…”
