- W4224297745 abstract "In this study, we report on novel optical chemosensors containing benzothiazole moeity, namely, 2‐(6‐chloro‐benzothiazol‐2‐yl azo)‐4‐methyl‐phenol (CBAMP) and 1‐(6‐chloro‐benzothiazol‐2‐yl azo)‐naphthalen‐2‐ol (CBAN), which were synthesized and characterized by Fourier transform infrared spectroscopy (FT‐IR), 1 H‐NMR, 13 C‐NMR, and mass spectrometry. The solvatochromic behavior was explored in different solvents of various polarities to explore the active fluorescent tautomer, and the photophysical parameters have been measured. The naked eyes, as well as ultraviolet–visible (UV–Vis) and fluorescence spectroscopy, were used to study the colorimetric and optical sensing properties of CBAMP and CBAN toward various metal ions and anions. These chemosensors have a strong detecting ability, with excellent sensitivity and selectivity for certain of the metal ions investigated, as well as CO 3 2− and CN − over other anions. The Benesi–Hildebrand and Job's plots were used to determine the binding constants and stoichiometry of the formed metal ions–sensor complexes, respectively. Co 2+ and Cu 2+ ions have lower detection limits in CBAMP and CBAN than other metal ions (6.4 × 10 −7 and 8.4 × 10 −7 M, respectively). Furthermore, fluorescent imaging investigations for Co 2+ and Cu 2+ ions in living cells reveal CBAMP and CBAN's promise for biological chemosensing." @default.
