A Water‐Stable Uranyl Organic Framework as a Highly Selective and Sensitive Bifunctional Luminescent Probe for Fe3+ and Tetracycline Hydrochloride

“…It can be systematically adjusted channels to give them excellent luminescence properties for the design and synthesis of specific fluorescentp robes. [14][15][16][17] Since first reported in 2002, MOFs fluorescent probes have mushroomed. [18,19] Many probesh ave been used to identify ions, smallo rganic molecules, biomacromolecules, and nitroaromatic explosives et al [20][21][22] Among numerous LMOFs, uranyl fluorescenceM OFs have the following characteristics compared with other LMOFs: [23][24][25][26][27] (1) The fluorescence lifetime is long, which is benefit to time resolution.…”

State of the art methods and challenges of luminescent metal–organic frameworks for antibiotic detection

“…Some relative LMOF thin films have been fabricated via various synthetic strategies. [124][125][126][127][128][129] A representative work has been reported by Zhang and co-authors. 124 film displayed different quenching efficiencies in various antibiotics and aqueous solutions, especially for NFT and NFZ, because the electron-deficient nitro-group can accelerate the electron transfer from MOF to both antibiotics.…”

“…From 2017, three examples of Ln(III)-based luminescence MMMs have been designed and prepared as indicators toward antibiotics in water. [127][128][129] For example, Zhang and co-authors reported on a Tb-MOF [Tb 2 (AIP) 2 (H 2 O) 10 ]•(AIP)•4H 2 O (Tb-AIP, AIP = 5-aminoisophthalate) with green luminescence, which was utilized as powder fillers to incorporate into the low-cost and clear polymer of poly(methyl methacrylate) (PMMA) chloroform solution. 127 The mixed slurry was further dropped onto the glass, and then dried in a 40°C oven overnight (Fig.…”
