A new-AIE-ligand-based metal–organic framework “turn-on” sensor with extremely high sensitivity

Abstract

The excessive Fe3+ and Bi3+ can cause serious hazard to human-being and microorganisms. However, it remains great challenging to exploit more efficient method to detect them. In this work, a...

Preparation of chiral metal–organic framework l-his-MIL-53-NH2@SiO2 composite by in situ growth and chiral post-modification strategies for HPLC enantiomeric separation

“…Metal–organic frameworks (MOFs) are periodic porous materials formed by self-assembly of metal ions or metal clusters with organic ligands. 1–3 Since MOFs are characterized by rich topology, adjustable pore size, controllable functional groups, and high specific surface area, they have a wide range of applications in catalysis, 4,5 gas storage, 6 separation, 7–9 drug delivery, 10,11 sensing, 12 and so on. As an important branch of MOFs, chiral metal–organic frameworks (CMOFs) with abundant chiral recognition sites and good spatial selectivity have been widely used in membrane separation, 13 chromatographic separation, 14,15 and asymmetric catalysis.…”

A photochromic Cd(ii)-organic framework showing highly efficient dual-response sensing properties

“…Luminescent MOFs have been developed as convenient and efficient sensor materials for detecting diverse pollutants such as NCs, cations, anions, volatile organic compounds, and so on. 33–39 These luminescent MOF-based sensor materials for the detection of hazardous substance are mostly constructed using transition metal building centers (Zn 2+ , Cd 2+ or RE 3+ ). 40–43 It is well known that functional organic ligands play key roles in the structures and properties of MOFs.…”
