“… − Time-dependent luminescence has been performed on the Eu 3+ @LCU-117 toward OTC (Figure c). Based on the result, all sensing activities showed fast response within 20 s. As far as we know, Ln 3+ post-modified MOF materials have generally been employed for chemisensors to detect antibiotics or other chemicals. ,− For example, very recently, He’s group reported one Eu 3+ -functionalized MOF named EuUCBA to detect TCs through luminescence quenching, which showed a low detection limit of 0.118 μM toward OTC . Simple mixing of Ln 3+ in suspensions with MOF as the chemisensor, to the best of our knowledge, has never been reported before.…”

It is necessary to find more simple methods to improve the detection selectivity and sensitivity of antibiotics. Herein, we constructed a novel three-dimensional (3D) Cd-MOF LCU-117 assembled from p-terphenyl-4,2″,5″,4′-tetracarboxylic acid, which showed a special 3D helical structure with carboxylic acid ligands and nitrogen-containing ligands crossing each other vertically. Luminescence measurements indicated that LCU-117 has high selectivity and sensitivity toward Eu3+ through the ratiometric effect. Meanwhile, this complex itself could detect antibiotics oxytetracycline (OTC) through the turn-off mechanism. When Eu3+ was added in suspensions of LCU-117 (noted as Eu3+@LCU-117), the detection toward OTC was enhanced significantly and visually. The sensing mechanism was investigated in detail by various measurements and theoretical calculations. LCU-117 has a good effect on the logic gate, potential fingerprint detection, and mixed-matrix membranes (MMMs). The practical application for monitoring OTC in water samples also provided a satisfactory result.

“…Further affirmation could be afforded by XPS spectra and EDS elemental mapping, as depicted in Figure S22a,b, where S element appears in the survey spectrum and O1s peaks show a 0.1 eV downward shift in MB-treated CaEuCAM. The diffraction peaks of Eu 3+ 3d 5/2 and Eu 3+ 3d 3/2 are observed at 1135.5 and 1165 eV in pristine CaEuCAM ,respectively, owing to multiple splitting of the spin−orbit j = 5/2 and 3/2 components, 90 which shift to 1132.5 and 1156.5 eV (Figure S22c) upon MB treatment. Meanwhile, the 2p diffraction peak of Ca 2+ exhibits 0.1 or 0.2 eV binding energy variations after MB adsorption (Figure S22d).…”

With increasing global industrialization, it is urgent and challenging to develop multifunctional species for detection and adsorption in the environment. For this purpose, a novel anionic heterometallic organic framework, [, is hydrothermally synthesized based on chelidamic acid (H 3 CAM). Single crystal analysis shows that CaEuCAM features two different oxygenrich channels along the c-axis in which one CAM 3− bridges two sextuplecoordinated Ca 2+ and two octuple-coordinated Eu 3+ with a μ 4 -η 1 : η 1 : η 1 : η 1 : η 1 : η 1 new chelating and bridging mode. The characteristic bright red emission and superior hydrostability of CaEuCAM under harsh acidic and basic conditions benefit it by acting as a highly sensitive sensor for Fe 3+ and 3nitrophenol (3-NP) with extremely low LODs through remarkable quenching. The combination of experiments and theoretical calculations for sensing mechanisms shows that the competitive absorption and interaction are responsible for Fe 3+ -induced selective emission quenching, while that for 3-NP is the result of the synergism of host−guest chemistry and the inner filter effect. Meanwhile, the assimilation of negative charge plus channels renders CaEuCAM a highly selective adsorbent for methylene blue (MB) due to a synergy of electrostatic affinity, ion-dipole interaction, and size matching. Of note is the reusability of CaEuCAM toward Fe 3+ /3-NP sensing and MB adsorption besides its fast response. These findings could be very useful in guiding the development of multifunctional Ln-MOFs for sensing and adsorption applications in water media.

“…Metal–organic frameworks (MOFs) are porous crystalline materials prepared by metal ions/clusters and organic ligands linking by coordination bonds. − MOFs have been intensively investigated for biochemical applications due to their distinctive physicochemical features including high thermal stability, high surface area, porosity, presence of cavities and functionality. − Many optical-based applications require stable, durable, and effective luminescent materials. , Luminescent metal–organic frameworks (LMOFs), as a part of the metal–organic frameworks (MOFs) family, are gaining great attention recently due to their enormous applications in bio(chemical) sensing and bioimaging. − Although many functionalizations of MOFs have been reported to prepare LMOFs, such as using fluorescent linker in MOF and/or insertion of luminophores into the MOF structure such as nanoclusters, carbon dot, and fluorescent dyes, the fabrication of MOFs with intrinsic luminescence is more practical and valuable for many applications due to stability of the MOFs and low-cost precursors . In the literature, for the construction of intrinsic LMOFs, lanthanide elements, such as Eu 3+ and Tb 3+ are used. ,,, Such elements have higher costs, potential supply shortages, and adverse effects on the environment.…”

Dual-state emitters (DSEs) are entities that exhibit fluorescence in both the solution and solid state, which open up a wide range of possibilities for their utilization in various fields. The development of detection platforms using intrinsic luminescent metal–organic frameworks (LMOFs) is highly desirable for a variety of applications. DSE MOFs as a subclass of intrinsic LMOFs are highly attractive due to no need for encapsulation/functionalization by fluorophores and/or using luminescent linkers. Herein, a highly stable intrinsic dual-state blue emission (λem = 425 nm) zinc-based MOF with rodlike nanostructures (denoted as UoZ-2) was synthesized and characterized. To the best of our knowledge, intrinsic DSE of Zn-MOFs with blue emission in the dispersed form in solution and solid-state fluorescence have not been reported yet. When tetracycline (TC) was added, a continuous color evolution from blue to greenish-yellow with dramatic enhancement was observed due to aggregation induced emission (AIE). Thus, a sensitive ratiometry-based visual detection platform, in solution and on paper independently, was designed for detection of TC exploiting the DSE and AIE properties of UoZ-2 alone and UoZ-2:TC. The detection limit was estimated to be 4.5 nM, which is considered to be one of the most sensitive ratiometric fluorescent probes for TC sensing. The ratiometry paper-based UoZ-2 sensor displays a reliable TC quantitative analysis by recognizing RGB values in the on-site TC detection with satisfactory recoveries.
