Article Abstract
Lanthanide metal-organic frameworks (Ln-MOFs) have temperature-responsive luminescent properties for sensing applications. In this study, we developed a dual-emission fluorescent label (SCF-TGIC@MOF) with temperature-responsive properties, achieved by doping epoxy-modified Eu-MOF (TGIC@Eu-MOF) into a sodium alginate/carboxymethylcellulose composite substrate containing fluorescein (SCF). The composites modified with triglycidyl isocyanurate (TGIC) showed improved fluorescence intensity, thermal stability, and relative sensitivity compared with unmodified Eu-MOF. The composite of the substrate improved the physicochemical stability of the label, while the label showed a visible green to red fluorescence transition corresponding to temperature changes in the physiological range (277.15-313.15 K). The responsiveness of the label to temperature suggests that it has the potential to be used as a luminescent thermometer. In addition, the monitored temperature range suggests that the smart label has value for applications in environmental temperature monitoring. And this may apply to the preservation and storage of food products, such as vegetables and aquatic products.

Separation of xylene isomers, serving as indispensable feedstock in the petrochemical industry, is important but significantly challenging due to their similar physicochemical properties. With readily tunable network structures and chemical functionalities, metal-organic frameworks (MOFs) are promising for separation and many other potential applications. Here, we computationally design 150 lanthanide-based MOFs with one-dimensional triangular nanopores by varying metal compositions.

Tetracycline (TC) residues in animal-derived food pose a significant threat to human health, necessitating the development of straightforward and user-friendly methods for TC detection to safeguard food safety. Here, a series of novel Eu-based metal-organic frameworks (Eu-MOFs) were prepared using a dual-ligand strategy. In the midst of these Eu-MOFs, Eu-ABPDC/BPDC exhibits the dual emission at 472 and 619 nm under single-wavelength excitation, enabling highly effective ratiometric fluorescence sensing of TC.

Perfluorooctanoic acid (PFOA) is a persistent organic pollutant with a global presence in water, air, and soil resources. Herein, a water-stable amine-functionalized lanthanide metal-organic framework () is utilized for ratiometric luminescence detection of PFOA. In the presence of PFOA, there is an increase in the emission intensity of the organic ligand, while the characteristic luminescence intensity of Eu ions decreases, accompanied by a distinct emission color change from red to blue.

A luminescent lanthanide metal-organic framework, [(TD)Eu(HCO)(DMF)] (Eu-TD, TD/HBTDB = 4,4'-(benzo[][1,2,5] thiadiazole-4,7-diyl)dibenzoic acid), was synthesized via a solvothermal method by coordinating Eu ions with the strongly emissive ligand HBTDB. Single-crystal X-ray diffraction analysis reveals that the Eu-TD is in the hexagonal system with space group 622. Eu-TD demonstrated exceptional selectivity toward Al ions, exhibiting remarkable sensitivity with a low detection limit (limit of detection (LOD) = 0.

Dual-signal-output ratiometric electrochemiluminescence (ECL) platforms offer a promising solution to address the instability and inaccuracies associated with single-signal ECL detection. However, most existing ratiometric systems still rely on two independent luminophores, inevitably increasing the system complexity and compromising the detection accuracy. In this study, a bimetallic dual-ligand ECL luminophore, Ce/Tb-MOF, was synthesized via a solvothermal approach, exhibiting distinct anodic and cathodic ECL emissions from a single luminophore.
