“…Several MOFs involving metals with ns or np valence electrons have been reported as luminescence sensors for metal ion detection. [249][250][251][252][253][254][255][256][257] For example, a series of luminescent MOFs involving tri-or tetravalent metal ions (Al 3+ , Zr 4 + , Cr 3+ , Fe 3+ , and Ti 4+ ) were synthesized and screened for simultaneous detection and removal of mercuric ions. [249] The Al-based MOF exhibited an excellent ability for Hg 2+ detection with wide response interval (1 −17.3 μM), low detection limit (0.15 μM), good selectivity, and wide pH adaptation (4.0−10.0).…”

“…[249] Gao and coworkers have recently found that the fluorescent complex [Al 8 (OH) 4 (OCH 3 ) 8 (BDC(OH) 2 ) 6 ]⋅ x H 2 O (CAU-1-(OH) 2 )] can be used as a fluorescent probe for bismuth ion (Bi 3+ ) detection in aqueous solutions. [250] While the MOF can exhibit bright green fluorescence in water due to the intramolecular proton transfer process, the carboxylate and hydroxyl groups in the MOF can strongly coordinate with Bi 3+ with low detection limit ~ 2.16 μM in less than 30 seconds. [250] Furthermore, the supermicroporous Zr-based MOF provides a dual colorimetric and fluorometric chemosensor for Bi 3+ ions in a heterogeneous mixture with multiple cations and anions.…”

Metal-organic frameworks (MOFs) are of great interest to researchers in chemistry and material science due to their various chemical and physical properties, which include high surface area, augmented adsorption/desorption kinetics, biocompatibility, and functional tunability. The structurally diverse 1-D, 2-D, and 3-D metalorganic frameworks have found applications in chemical sensing and several other fields, such as energy applications, biomedicine, and catalysis. In this review article, we address recent research advances in the use of metal-organic-framework-based nanocomposite materials as luminescent sensors for detecting various metal ions in aqueous biological and environmental samples.

“…[ 4‐7 ] Particularly, thanks to abundant conjugated systems, designable binding sites, and regular frameworks structures, MOFs as sensory materials were widely used to detect guest ions or molecules. [ 8‐10 ] Recently, exploiting MOF sensors by taking advantage of the reversibility and instability in certain conditions of coordination bonds has become a research hotspot. [ 11‐14 ] For phosphate sensing, one of the current strategies is to utilize the coordination effect between phosphate and inorganic clusters to control the luminescence of MOFs, and the distinct binding of central metals towards phosphate is the dominant reason for the high selectivity.…”

Metal-organic frameworks | Fluorescent probes | Phosphate | Monodentate ligand | AIEgen Herein, a novel sensor (TPE-UiO-66) was designed via anchoring monodentate tetraphenylethylene (TPE) onto UiO-66 framework. The combination of the distinct aggregation-induced emission (AIE) of TPE and the easy replacement of monodentate linker by guest phosphate, makes TPE-UiO-66 an ideal platform for sensing HPO 4 2-. Experimental results indicate that TPE-UiO-66 can selectively sense HPO 4 2from other common anions. The limit of detection (LOD) can reach to 5.56 μmol•L-1 and more importantly, TPE-UiO-66 also exhibits an ultra-fast equilibrium response of 2 min, far faster than those of other sensors especially for UiO-66-NH 2. The combination of experimental analysis and density functional theory (DFT) calculations demonstrates that the high selectivity, high sensitivity and fast response of HPO 4 2detection by TPE-UiO-66 can be attributed to the stronger coordination interactions of HPO 4 2with Zr-O cluster of UiO-66 than that of TPE molecule. This study not only provides a potential probe for phosphate, but also represents a novel strategy to design stimuli-responsive fluorescent MOF-based sensors via using monodentate AIEgens.

“…In contrast, the fluorescence technique is more userfriendly and still can provide high sensitivity and selectivity. There have been several reports on the design and application of bismuth fluorescent sensors based on a metal-organic framework, (24) and functionalized naphthalimide, (25) rhodamine, (26,27) hydroxyquinoline (28) and pyrene (29).…”

Three pyreno[4,5‐d]imidazole derivatives are synthesized and evaluated as fluorescent sensors for bismuth (III) ion. The target compounds are prepared in 55–86% yields from a condensation reaction between pyrene‐4,5‐dione and aromatic aldehydes. The compound bearing a phenolic group can selectively detect bismuth (III) ion via fluorescence enhancement with a detection limit of 1.20 μm in CH3CN‐DMSO mixture and 3.40 μm in 10% pH5 aqueous in CH3CN‐DMSO mixture. The sensing mechanism involving a formation of coordination complex is investigated by UV‐VIS and fluorescence titrations, 1H‐NMR and the decomplexation of the bismuth complex by sulfide ion. The application of this sensor for quantitative analysis of spiked bismuth (III) ion in real water samples from two different sources is demonstrated.
