| Abstract | AbstractTo develop an effective fluorescent chemosensor for relay recognition of Zn2+ and oxalate, a new fluorescent sensor based on binaphthol-quinoline Schiff base L1 was designed and synthesized. In DMSO-H2O (1/1, v/v, HEPES 10 mM, pH = 7.4) solution, L1 exhibits highly selective fluorescence turn on response to Zn2+ over other metal ions. The Zn2+ recognition event is barely interfered by other coexisting metal ions except Cu 2+, Co 2+ and Ni 2+. The in situ generated L1-Zn2+$^{\mathrm {2+}}_{\mathrm {}}$complex was further used as a chemosensing ensemble for oxalate detection. The complex L1-Zn2+ displays high selectivity to oxalate with significant fluorescence quenching through Zn2+ ion displacement approach. In addition, application of L1 for imaging of Zn2+ and oxalate in living HeLa cells was also examined. Graphical AbstractA new binaphthol-quinoline Schiff base-based fluorescent sensor L1 exhibits highly selective relay recognition of Zn2+ and oxalate through fluorescence “off-on-off” functionality in DMSO-H2O (1/1, v/v, HEPES 10 mM, pH = 7.4) solution. |
