Summary: Design and development of simple, affordable and 'turn-ON' fluorescent probes for fluoride ion sensing is an incessant research target over the decades. In this study, new benzothiophene derivatives were developed as selective fluorescent probes for trace-level fluoride ion detection. The mechanism of fluoride ion detection was elucidated using H-1 NMR and FT-IR investigations, and the experimental results were validated using an Arduino-based platform.

Summary: Proper amount of fluorion is important for human health, but excessive fluorion is harmful. A colorimetric and fluorescence enhanced sensor, using MOF material UiO-66 combined with fluorescent dye FITC, is proposed to detect fluorion with high selectivity. It has a good linear relationship in the range of 2-150 mu M (0.038-2.85 ppm), and has been applied to the detection of actual water samples. Field visual detection of fluoride ion is realized, expanding the application of MOF in fluorescence sensing.

Summary: Cost-effective fluorescence turn-on indicator-displacement-assay (IDA) sensors based on octamethylcalix[4] pyrrole receptor and tetrabutylammonium salts of 4-methylumbelliferone and fluorescein indicators were developed for highly sensitive detection of fluoride anion. The IDA sensors demonstrated rapid and selective sensitivity towards fluoride, with color change observed in the 4-methylumbelliferone system. The fluorescein-based IDA sensor showed a detection limit as low as 3.2 nM for fluoride anion detection.

Summary: The development of an effective and selective chemosensor for CN- ions is urgently needed due to their hazardous impact. Two novel chemosensors, IF-1 and IF-2, based on 3-hydroxy-2-naphthohydrazide and aldehyde derivatives, have been synthesized and shown selective sensing of CN- ions. IF-2 exhibited exclusive binding with CN- ions, confirmed by a binding constant value of 4.77 x 10(4) M-1 and a low detection limit (8.2 μM). The color change from colorless to yellow, visible by the naked eye, is attributed to the deprotonation of the labile Schiff base center by CN- ions.

Summary: Due to its high electron density, fluoride anions are the most effective halogen bond acceptors among the halides. However, under common experimental conditions, fluoride ions rarely act as acceptors, possibly due to their hydrated form. Here, we report that under specific crystallization conditions, a hydrogen bond-free fluoride ion acting as an electron density donor can be obtained, and the resulting halogen bonds play a significant role in the observed crystal packings. Computational studies confirm the strength of these halogen bonds compared to similar interactions involving other halides.

Summary: Imidazolium-based receptors selectively recognize anions and have gained more attention in the past decade. New developments in this field include new imidazolium motifs and the identification of a wider variety of biological anions. The progress from 2010 to 2019 focuses on classifying receptors based on motifs and discussing different types of anions separately.

Summary: We synthesized a symmetrical N,N'-bis(3-(1H-imidazol-1-yl)propyl)oxalamide-based receptor OX(PID)(2) and characterized it using various physicochemical techniques. The receptor exhibited high selectivity and sensitivity towards Cu2+ and Fe3+ ions and showed cytotoxicity against MDA-MB-231 cells, suggesting its potential as an anticancer agent. The biological activities of the newly created oxalamide-based compounds were evaluated against pathogenic bacteria, showing moderate to good antibacterial activity.

Summary: In the past two decades, the development of novel anion receptors and sensors has been driven by the ubiquitous presence of anions in biological and environmental systems. Optical anion sensors, known for their simple technology and fast response time, have become particularly popular. Macrocyclic host molecules and mechanically interlocked host molecules have shown promising anion binding properties, making them ideal candidates for the development of optical anion sensors.

Summary: Thin film coatings with potent antibacterial properties are widely used in medical devices, frequently touched surfaces, and food packaging. However, achieving antibacterial performance under both light and dark conditions remains a challenge. In this study, we successfully prepared AgBr-coated ZnO nanorod thin film architecture using a unique surfactant-mediated solution-phase spin-coating approach. The resulting structures showed dual functionality as antimicrobial agents and photosensitizers, effectively enhancing the visible-light photodisinfection efficacy of ZnO nanorods. The concentration of the surfactant-based precursor solution could be modulated to control the AgBr content. Additionally, components like urea and lactic acid were found to enhance the photocatalytic efficiency of the structures.
