Summary: HNA is a dual-platform colorimetric and ratiometric chemosensor designed to detect fluoride anion in DMSO solution. It shows excellent selectivity and sensitivity, with color changes from yellow to purple when F- is present. The detection limit is as low as 0.61 mu M, and it has a binding model with F- in a 3:2 stoichiometry ratio. HNA has the potential to be a superior chemosensor for monitoring F- selectively and sensitively.

Summary: A Schiff base receptor with an active -NH group was synthesized for the colorimetric detection of inorganic fluoride (F-) ions in an aqueous medium. The receptor showed enhanced sensitivity for F- ions due to the presence of electron-withdrawing -NO2 groups, resulting in a remarkable color change. Characterization techniques confirmed the structural integrity of the synthesized receptors and a binding mechanism involving deprotonation of the -NH group and formation of -HF2 was proposed.

Summary: Industrial activity has caused widespread metal ion pollution, leading to concerns for ecosystems and human health. Therefore, it is crucial to develop sensors that can selectively and sensitively detect these analytes. In this study, an azo dye, Dabcyl 2, was synthesized and tested for its ability to detect metal ions with environmental and industrial relevance. The results showed that chemosensor 2 had a selective response for Pd2+, Sn2+ and Fe3+, with a visible color change and significant shifts in the UV-Vis spectrum.

Summary: In this study, an azo-functionalized zirconium metal organic framework grafted on carboxymethylated cellulose membrane (UiO-66-Azo-Im@CCM) was synthesized using a solvothermal method. The developed sensor was thoroughly characterized and its sensitivity, selectivity, and ratiometric properties were investigated. The study demonstrated that the UiO-66-Azo-Im@CCM sensor showed excellent performance in terms of sensitivity, selectivity, and ratiometric properties towards copper, cobalt, and nickel heavy metal ions. The sensor had a lower limit of detection for these heavy metal ions than the permissible concentration set by the World Health Organization, indicating its potential for monitoring these heavy metals.

Summary: A ratiometric fluorescent probe BTEP based on 2-(2'-hydroxyphenyl)benzimidazole (HBI) was successfully synthesized using 5-bromosalicylaldehyde via Sonogashira coupling and condensation reaction. This probe is designed for rapid detection of boron trifluoride solutions and gases. The fluorescence emission of the probe undergoes a blue shift due to the boron difluoride addition with BF3, which affects the excited state intramolecular proton transfer (ESIPT). The probe shows a linear relationship between the I-408/I-479 fluorescence ratio and the concentration of BF3 in the range of 5-50 μM, with a low detection limit of 69.5 nM. Among eight common interference substances, the probe exhibits specific and selective recognition of BF3. Test strips prepared with BTEP have the ability for real-time naked-eye detection of trace BF3 gas.

Summary: A new series of sensors (SM-1 to SM-3) were synthesized using indole carboxaldehydes and 2,4-dinitrophenyl hydrazine. The deprotonated chromophores exhibited a smaller band gap and a red shift compared to the neutral sensors. Charge transfer from indole to dinitrophenyl hydrazine was observed. Sensor SM-3 showed high selectivity for F- ions, while SM-1 and SM-2 responded to both F- and CN- ions.

Summary: The highly selective sensor BBCN based on BINOL has been developed for ratiometric fluorescent detection of cyanide ions (CN-), showing a unique spectral change and color shift from green to blue in the presence of CN-. The detection limit is reasonably low at 189 nM, with a linear relationship between the fluorescence ratiometric ratio of BBCN and CN- concentration. The optical response is due to the nucleophilic addition of CN- to the dicyanovinyl group of the sensor, compromising the intramolecular charge transfer.
