'Naked-eye' quinoline-based 'reactive' sensor for recognition of Hg²⁺ ion in aqueous solution.

Abstract：

:A new 'naked-eye' quinoline-based 'reactive' ratiometric fluorescent probe was prepared. The reactive stoichiometry of the probe with Hg²⁺ ion was 2:1. The probe exhibited high selectivity towards Hg²⁺ ion to other metal ions with a 410-fold increase in absorbance intensity ratio (A₄₀₂/A₃₄₀) in aqueous solution over a wide-range pH value (2-12), accompanied by a resonance color change from colorless to pale yellow visible to naked-eye.

  • Topological estimation of electronic absorption bands of arene absorption spectra as a tool for modeling their toxicity and environmental pollution.

    abstract：:A novel application of distance-based topological indices : Wiener (W)-, Szeged (Sz)-, Padmakar-Ivan (PI)-, and Sadhana (Sd)-indices in modeling electronic absorption bands of arene absorption spectra has been described. It is demonstrated that all these indices correlate linearly with the logarithm of beta and para e...
