Two entangled photoluminescent MOFs of naphthalenedisulfonate and bis(benzimidazole) ligands for selective sensing of Fe3+

A calixarene-based coordination cage as an efficient luminescent sensor for Fe3+, MnO4−, NB and 2,4-DNP in aqueous medium

“…PCCs have attracted great attention because of their intriguing structures and widespread applications in gas storage 18,19 and separation, 20,21 catalysis, [22][23][24] drug delivery 25 and guest encapsulation. [26][27][28] Metal-organic frameworks (MOFs) have proved to be excellent fluorescent sensors and have been widely used to detect cations, [29][30][31][32] anions, [33][34][35] nitrogen-containing compounds 36,37 and organic molecules 38,39 in the environment. However, as a typical unit for an infinitely connected MOF, PCCs serving as fluorescent probes have rarely been discussed.…”

Multifunctional Fluorescence Turn-On Sensor for Acetylacetone, Glyoxal, and Salicylaldehyde Based on a Highly Stable 1D → 2D Interlocked Cd(II) Metal–Organic Framework

“…Through structural entanglement, MOFs could expand the surface area in the framework to improve the adsorption capacity, or divide large cavities into small space to maximize stacking efficiency, thus improving the thermal and chemical stability. , Interlocked MOF is a kind of entangled MOF to require the existence of closed rings in the chain . A long and curved organic ligand is usually selected to construct the interlocked MOF, which has easy to form large cavity structures . Another organic ligand with fluorescent groups could be introduced to connect closed loops to enrich the structure of the interlocked MOF and enhance the luminescent properties.…”

“…32 A long and curved organic ligand is usually selected to construct the interlocked MOF, which has easy to form large cavity structures. 31 Another organic ligand with fluorescent groups could be introduced to connect closed loops to enrich the structure of the interlocked MOF and enhance the luminescent properties. The good stabilities and luminescence properties are favorable for interlocked LMOFs to be used as chemical sensors to detect harmful substances.…”

Study on the host–guest complex of dicyclohexanocucurbit[6]uril and 2-phenylbenzimidazole, and its recognition effect toward Fe 3+

“…Benzimidazole compounds [1][2][3][4][5] are aromatic heterocyclic compounds containing two nitrogen atoms. Benzimidazole derivatives and metal complexes exhibit good biological activity.…”
