Summary: A new rhodamine-6G hydrazone (RHMA) was synthesized using rhodamine-6G hydrazide and 5-Allyl-3methoxysalicylaldehyde. RHMA was fully characterized and showed selective recognition of Cu2+ and Hg2+ among other metals. The absorbance and fluorescence of RHMA changed significantly with the presence of Cu2+ and Hg2+, resulting in a visual color change. RHMA also showed reversibility in the presence of EDTA2- ions and can be applied as a test strip for detection.

Summary: Novel naked eye chromofluorogenic chemosensors based on 5-chloro-2-hydroxy-, 3,5-dichloro-2-hydroxy-, and 3-bromo-2-hydroxy-5-methoxybenzylidene azomethine imines were synthesized and studied for their structure and sensing properties. The compounds exhibited low-intensity emission at specific wavelengths, which were completely quenched in the presence of F-, CN-, AcO-, and H2PO4- ions. The sensing mechanism was attributed to the formation of hydrogen bonds with the anions, resulting in a color change and intense fluorescence.

Summary: We fabricated a new rhodamine-based switch-on fluorescent and colorimetric chemosensor (RHEN) for the determination of Hg2+. The RHEN showed a noticeable colorimetric response for the presence of Hg2+, changing from colorless to pink under daylight. The fluorescence intensity of RHEN was remarkably enhanced and the color changed to dusty rose under UV light when exposed to Hg2+. The RHEN exhibited excellent sensitivity, specificity, and selectivity for Hg2+ detection, with a low detection limit of 0.11 μm. The binding phenomenon between RHEN and Hg2+ was identified using various spectroscopic techniques. Moreover, RHEN was successfully applied for Hg2+ detection in fish samples, as well as for test-paper and cotton swab applications. Smartphone application demonstrated that RHEN can serve as a powerful tool for on-site sensing of Hg2+ without the need for complicated devices.

Summary: We designed and synthesized a new near-infrared ratiometric fluorescent probe for monitoring mercury ions based on quinoline-fused rhodamine dye. The probe shows a ratiometric fluorescent change after treatment with mercury ions, with increased emission in the near-infrared region and significantly reduced emission in the visible region. The probe has remarkable detection selectivity, fast response, and high detection sensitivity, and can be applied as a detection tool for mercury ions with dual-channel ratiometric fluorescence imaging in living cells.

Summary: Fluorine-19 MRI is a promising technique for biomolecular imaging, but its poor sensitivity has been a limitation. To increase the sensitivity, increasing the number of fluorine nuclei per probe and decreasing their relaxation time are necessary. This can be achieved by using fluxional lanthanide complexes with open coordination sites. The results show that these complexes can bind fluorinated phosphonates, resulting in chemically equivalent fluorine nuclei and improved imaging performance.
