Abstract
Effective detection of pollutants in water is of great significance for environmental detection. In this study, the complex {[Zn(Hbsal)2(dpa)]·2CH3CH2OH}n (1) (H2bsal = 5-bromosalicylic acid, dpa = bis(4-pyridyl)amine) was successfully synthesized by hydrothermal synthesis method. 1 exhibits strong fluorescence emission, excellent anti-interference capability, and good reusability, making it an ideal material for the detection of aqueous-phase pollutants. The experimental results show that 1 has specific sensing recognition for Cr3+, LVX, and Cys, and the limits of detection (LOD) are 2.86 × 10−5 M, 2.51 × 10−5 M, and 5.84 × 10−5 M. These results indicate that 1 can be used as sensing fluorescent probes for Cr3+, LVX, and Cys in aqueous solution and has broad application prospects in environmental detection.
A novel methylthiazole-quinolinol-based sensor (MTAMQ) named (E)-2-methyl-5-((4-methylthiazol-2-yl)diazenyl)quinolin-8-ol was synthesized. In the presence of copper(II) ions (Cu2+), the MTAMQ sensor exhibits a stable color change from yellow to red. The MTAMQ sensor displayed a linear response toward Cu2+ ions over the...
Copper is an essential trace element involved in key biological and environmental processes; however, its imbalance can lead to severe health and ecological consequences, making its accurate quantification crucial. In this work, a two-component colorimetric and fluorescent sensing platform based on the imine derivative...

The accurate determination of multiple heavy metal ions (HMIs) is of great significance due to their high toxicity and environmental persistence. Herein, a novel Mn3-cluster-based metal organic framework, namely [Mn3L3·4DMF]·4CH3CN·2H2O (1-Mn), has been synthesized via a solvothermal method (L = 2,2'-(1,4-Phenylenebis(...

In this study, a Schiff base-derived Pd(II) complex (L–Pd) was successfully synthesized and investigated as a fluorescent sensor for the detection of 2,4,6-trinitrophenol (TNP), a highly hazardous nitroaromatic explosive pollutant. Fluorescence studies demonstrated that the L–Pd complex exhibits strong emission propert...

Developing a low-cost, highly sensitive, and accurate fluorescence-based approach for Cu2+ detection is crucial for reducing heavy metal pollution in industrial effluent. Here, we report a newly synthesized Schiff base europium metal-organic framework (Eu-MOF) and demonstrate its use for turn-off fluorescent detection...

The rapid and accurate detection of antibiotics and disease biomarkers is crucial for disease prevention, diagnosis, and treatment. Herein, a novel multidentate ligand containing a benzothiadiazole unit, namely, 4,7-bis(1H-imidazol-1-yl)benzo-[2,1,3]thiadiazole (BIBT), together with 4,4'-stilbenedicaroxylic acid (H2SBC...
