title: Synthesis of Schiff base-Based 1,2,4-Oxadiazole Derivative as Fluorescence Turn-On Sensor for High Selectivity of Pb(2.).
abstract: A new probe based on oxadiazole derivative (OXD) containing Schiff base moiety was synthesised as fluorescence turn-on sensor S1 . Furthermore, its fluorescents spectra (FS) result demonstrate that S1 selectively senses bivalent lead ion (Pb(2+)) in HEPES buffer solution (10 mM, pH = 7.0,DMF-H2O, 9:1, v/v), so S1 was a viable candidate as fluorescent receptor for a new Pb(2+) sensor. And the results of fluorescent spectral titration showed this sensor formed 1:1complex with Pb(2+).
