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+).
合成了一种基于含席夫碱部分的恶二唑衍生物（OXD）的新型探针作为荧光开启传感器S1。此外，其荧光光谱（FS）结果表明，S1在HEPES缓冲溶液（10 mM，pH = 7.0，DMF-H2O，9:1，v/v）中能选择性地检测二价铅离子（Pb(2+)），因此S1作为新型Pb(2+)传感器的荧光受体是一个可行的候选物。荧光光谱滴定结果表明该传感器与Pb(2+)形成了1:1的配合物。
