“…Hc(–CH=N) 9.07 ppm shifted to Hc′ (9.09 ppm) by 0.02 ppm, which might be due to the formation of an N–Zn 2+ coordination bond. [ 47–49 ] The combination of 1o ‐Zn 2+ was verified by mass spectrometric analysis, and 1o ‐Zn 2+ had a peak at m/z 860.0278, [ 1o + Zn 2+ + CH 3 CN − H + ] + (Figure S7). According to the earlier results, the coordination pattern of Zn 2+ with 1o was simulated.…”

In view of the fluorescent switching properties and anti-fatigue properties of diarylethene, a diarylethene fluorescent chemosensor for the immediate detection of zinc ion (Zn 2+ ) and magnesium ion (Mg 2+ ) in acetonitrile was synthesized in this article.The structure of 1o was determined by performing spectroscopy and elemental analysis. The presence of Zn 2+ or Mg 2+ made the chemosensor 1o show an obvious "turn-on" fluorescent signal (bright yellow-green for Mg 2+ and bright cyan for Zn 2+ ).The fluorescent change caused by the 1:1 binding of 1o and Zn 2+ or Mg 2+ might be due to hindering the excited-state intramolecular proton transfer (ESIPT) process, which were bolstered by Benesi-Hildebrand analysis, Job's plot curves, proton nuclear magnetic resonance ( 1 H-NMR) titration and mass spectrometry. The limits of detection were acquired from the standard curve plots for Mg 2+ at 44.6 nM and for Zn 2+ at 14 nM. Based on the fluorescent behaviors, a logic gate was constructed with the emission intensity at 528/518 nm as output signal, the ultraviolet-visible (UV-vis) lights, Mg 2+ /Zn 2+ and EDTA as input signals. Exogenous Zn 2+ and Mg 2+ fluorescent bioimaging were performed on Hela cells with 1o, indicating its potential application in biodiagnostic analysis. In particular, 1o was manufactured into test paper, and Zn 2+ or Mg 2+ can be conveniently, efficiently and qualitatively identified by the fluorescent color variation of the test strips.

“…[10,15,16] Due to relative environmental concerns and health issues of living things, developing sensitive and selective fluorescent chemosensors for Ag + is highly desirable. [17][18][19] Many probes have been reported for Ag + ion detection. Among them, azines (=NÀ N=) and azine derivatives have desirable ligand properties towards metal ions and are very potential probes, capable of detecting transition and posttransition metal ions in the chemosensor study because of their =NÀ N= and À C=NÀ moieties.…”

A novel azine monomer and its oligomeric esters were synthesized and applied to chemosensor applications. Among the series of metal ions, the fluorophores show selective and sensitive “turn off” response towards Ag+ ions. The stoichiometry and binding constant are calculated using the Stern‐Volmer equation and Benesi‐Hildebrand plots, respectively. The fluorophore‘s capability for quantitative analysis of Ag+ ions was studied. The quenching mechanism LMCT and PET behind the “turn off” response was confirmed. The conductivity nature of iodine doped and undoped oligoesters was studied. The dielectric behaviour of oligoesters was also studied to determine the possibility of oligoesters in making passive components such as capacitors and resistors. All the results obtained from chemosensor and electrical studies were validated using a theoretical (DFT) analysis using B3LYP/6–311++G(d,p) level basis set.

An oxadiazole derivative 2 was prepared by condensation reaction through cyclization of semicarbazone in the presence of bromine; the structural confirmation was supported by 1H and 13C nuclear magnetic resonance (NMR) spectroscopy, Fourier transform‐infrared spectroscopy, and liquid chromatography‐mass spectrometry. Its sensing ability towards Ni2+ ion was examined showing a binding constant of 1.04 × 105 compared with other suitable metal cations (Ca2+, Co2+, Cr3+, Ag+, Pb2+, Fe3+, Mg2+, and K+) using ultraviolet–visible (UV–vis) and fluorescence spectroscopic studies. The minimum concentration of Ni2+ ions and limit of detection was found to be 9.4 μM. A job's plot gave the binding stoichiometry ratio of oxadiazole derivative 2 vs Ni2+ ions as 2:1. Furthermore, the intercalative binding mode of oxadiazole derivative 2 with calf thymus DNA was supported by ultraviolet–visible (UV–vis) and fluorescent light, viscosity, cyclic voltammetry, time‐resolved fluorescence, and circular dichroism measurements. The molecular docking result gave the binding score for oxadiazole derivative 2 as −6.5 kcal/mol, which further confirmed the intercalative interaction. In addition, the antifungal activity of oxadiazole derivative 2 was also screened against several fungal strains (C. albicans, C. glabrata, and C. tropicalis) by broth dilution and disc diffusion methods. In antioxidant studies, the oxadiazole derivative 2 showed potential scavenging activity against 2,2‐diphenyl‐1‐picrylhydrazyl and H2O2 free radicals.
