A Hydrophilic Mixed Lanthanide Metal–Organic Framework Monitoring H₂O in D₂O

Lanthanide metal–organic framework (Ln-MOF) luminescent sensors monitoring the H2O content in D2O are still rare. We designed and built a hydrophilic mixed Ln-MOF (Eu0.4Tb0.6-MOF) monitoring the H2O content in D2O. By designing a ligand and controlling the synthesis method, we achieved a balance between the structural stability and sensing capacity. When the H2O content ranges from 0 to 100%, the photoluminescence color of Eu0.4Tb0.6-MOF can change from yellow to green, which can be observed by the naked eye. The mechanism is that the photoluminescence intensity of Eu3+ decreases faster than that of Tb3+ when the H2O content increases. The sensing mechanism was studied further by transient fluorescence spectrometry

Construction of Multifunctional Luminescent Lanthanide MOFs for Luminescent Sensing of Temperature, Trifluoroacetic Acid Vapor and Explosives

Metal–organic frameworks (MOFs) with multifunctional and tunable optical properties have unique advantages in the field of sensing, and the structure and properties of MOFs are significantly influenced by the ligands. In this study, a Y-type tricarboxylic acid ligand containing amide bonds was synthesized through functional guidance, and three isomorphic and heterogeneous three-dimensional MOFs (Eu-MOF, Tb-MOF, and Gd-MOF) were obtained by solvothermal reaction. Further studies revealed that both the Tb-MOF and Eu-MOF could selectively detect picric acid (PA). The luminescence quenching of the two MOFs by PA was attributed to competing absorption and photoelectron energy transfer mechanisms. In addition, due to the energy transfer between Tb and Rhodamine B, Rhodamine B was encapsulated into Tb-MOF. The obtained material exhibited a linear relationship between the temperature parameters I544/I584 and temperature within the range of 280–400 K, the correlation coefficient (R2) reached an impressive value of 0.999, and the absolute sensitivity of the sample used for temperature sensing was 1.534% K–1. What is more, the material exhibited a good response to trifluoroacetic acid vapor, which suggests the potential of the material for temperature sensing and detection of trifluoroacetic acid vapor. The designed and investigated strategy can also serve as a reference for further research on excellent multifunctional sensors

A Highly Selective Fluorescent Sensor for Distinguishing Cadmium from Zinc Ions Based on a Quinoline Platform

A fluorescent sensor, <i>N</i>-(quinolin-8-yl)-2-(quinolin-8-yloxy)­acetamide (<b>HL</b>), based on 8-aminoquinoline and 8-hydroxyquinoline platforms has been synthesized. This sensor displays high selectivity and sensitive fluorescence enhancement to Cd²⁺ in ethanol. Moreover, sensor <b>HL</b> can distinguish Cd²⁺ from Zn²⁺ via two different sensing mechanisms (photoinduced electron transfer for Cd²⁺; internal charge transfer for Zn²⁺). The composition of the complex Cd²⁺/<b>HL</b> or Zn²⁺/<b>L</b>^– has been found to be 1:1, based on the fluorescence/absorption titration and further confirmed by X-ray crystallography

Na₂CaSn₂Ge₃O₁₂: A Novel Host Lattice for Sm³⁺-Doped Long-Persistent Phosphorescence Materials Emitting Reddish Orange Light

A novel host lattice disodium calcium ditin­(IV) trigermanium oxide Na₂CaSn₂Ge₃O₁₂ was utilized for synthesizing long-persistent phosphorescence materials for the first time. Reddish orange long-persistent phosphorescence was observed in Na₂CaSn₂Ge₃O₁₂:Sm³⁺ phosphors with persistence time more than 4.8 h. The phosphors were synthesized by a conventional solid-state reaction pathway in air atmosphere. A predominant cubic phase of Na₂CaSn₂Ge₃O₁₂ was observed in all XRD patterns. Photoluminescence measurements indicated that the emission spectrum was composed of the peaks located at 566 (the strongest), 605, 664, and 724 nm. The results of the decay curves in terms of a biexponential model suggest that different defects appear in the crystal lattice. The defects acting as traps were investigated by thermoluminescence, which demonstrated that doping Sm³⁺ ions into the Na₂CaSn₂Ge₃O₁₂ host has made the trap types abundant. Furthermore, the origin of the long-persistent phosphorescence has also been discussed. On the basis of the above results, Sm³⁺-doped Na₂CaSn₂Ge₃O₁₂ phosphors are considered to have potential practical applications
