A benzhydrazide Schiff-base fluorescent probe (1) for selectively detecting Zn2+ was synthesized and characterized by FT-IR, 1H NMR, 13C NMR, and high-resolution mass spectrometry (HRMS). This probe could emit blue light with a fluorescence enhancement under a 365 nm UV light after adding Zn2+ in solution. It showed a good linear relationship (y = 840.01x + 180.84, R2 = 0.9891) between fluorescence
合成了用于选择性检测Zn 2+的苯肼肼席夫碱荧光探针(1),并通过FT-IR,1 H NMR,13 C NMR和高分辨率质谱(HRMS)对其进行了表征。在溶液中添加Zn 2+后,该探针可在365 nm紫外线下发出具有荧光增强作用的蓝光。荧光强度与Zn 2+浓度(0.1–1.1×10 -5 mol / L)之间具有良好的线性关系(y = 840.01 x + 180.84,R 2 = 0.9891),检出限(LOD)为1.13×10 -3μM,该方法可用于检测竹笋中锌的含量。同时,溶液中的1 -Zn 2+系统也可用于确定溶液中的S 2-(y = -1685.3 x + 1062.8,R 2 = 0.9975,0.1–0.6 ×10 -5 mol / L)。这有一个骤冷法的线性关系,提供了1.66×10的LOD -4 μM。该探针具有较低的细胞毒性,可用于识别活Ln229和SW480细胞中Zn
