“…The 1:1 binding ratio was also confirmed by Benesi–Hildebrand plot shown in Figure . From the fluorescence titration curve (from Figure ), the association constant was calculated to be Ka = 1.0 × 10 6 M –1 . This result indicates a good binding attraction obtained between the ligand 4PB and Ba 2+ .…”

A phenoxazine-based fluorescence chemosensor 4PB [(4-(tert-butyl)-N-(4-((4-((5-oxo-5H-benzo[a]phenoxazin-6-yl)amino)phenyl)sulfonyl)phenyl)benzamide)] was designed and synthesized by a simple synthetic methods. The 4PB fluorescence chemosensor selectively detects Ba2+ in the existence of other alkaline metal ions. In addition, 4PB showed high selectivity and sensitivity for Ba2+ detection. The detection limit of 4PB was 0.282 μM and the binding constant was 1.0 × 106 M–1 in CH3CN/H2O (97.5:2.5 v/v, HEPES = 1.25 mM, pH 7.3) medium. This chemosensor functioned through the intramolecular charge transfer (ICT) mechanism, which was further confirmed by DFT studies. Live cell imaging in MCF-7 cells confirmed the cell permeability of 4PB and its capability for specific detection of Ba2+ in living cells.

A new designed fluorescent chemosensor TYMN ((E)-1-((thiazol-2-ylimino)methyl) naphthalen-2-ol) for highly sensitive and selective tracing of trace amount of Zn 2+ ions in some real samples was synthesized and characterized. The sensor TYMN can detect Zn 2+ ions via fluorescence enhancement with a high selectivity over a wide range of metal ions, especially Cd 2+. The sensor showed large fluorescence enhancement upon complexation with Zn 2+ and simultaneous color change from yellow to orange. The limit of detection was analyzed to be 0.0311 μM with a linear dynamic range 0.1-1.0 μM. The sensor could work in a pH span of 5.0-8.0. Based on the physicochemical and analytical methods like electrospray ionization (ESI)-mass, Job plot, 1 H nuclear magnetic resonance (NMR) and theoretical calculations, the detection mechanism for Zn 2+ was explained based on restriction of internal charge transfer (ICT) mechanism. TYMN sensor was potentially utilized for Zn 2+ ions concentration evaluation in some real samples. Fluorescence microscopy experiments revealed that probe TYMN may have application as a fluorophore to detect the Zn 2+ in living cells.

“…Fluorescence chemosensor design is the key topic in the determination of ions in biological processes. It is important to examine the fluorescence properties of the compounds to be synthesized as new sensors, their location in living organisms, and their usability for metal ion detection as fluorescent sensors [1][2][3]. Fe 3+ , an indispensable element for life, both provides oxygen-forming capacity and serves as a cofactor in many enzymatic reactions in the mitochondrial respiratory chain, and both deficiency and excess amounts of Fe 3+ can cause various diseases [4].…”

The newly synthesized cyclotriphosphazene cored coumarin chemosensors 5, 6, and 7 were successfully characterized by 1 H NMR, 31 P NMR, and MALDI-TOF mass spectrometry. Additionally, the photophysical and metal sensing properties of the targeted compounds were determined by fluorescence spectroscopy in the presence of various metals (Li + , Na + , K + , Cs + , Mg 2+ , Ca 2+ , Ba 2+ , Cr 3+ , Mn 2+ , Fe 3+ , Co 2+ , Al 3+ , Hg + , Cu 2+ , Zn 2+ , Ag + , and Cd 2+ ) . The fluorescence titration results showed that compounds 5, 6, and 7 could be employed as fluorescent chemosensors for Fe 3+ ions with high sensitivity. The complex stoichiometry between final cyclotriphosphazene chemosensors and Fe 3+ ions was also determined by Job’s plots.
