A quinoline-based fluorescence probe has been prepared and characterized. Probe 1 showed a selective sensing ability for Al and Fe ions through fluorescence enhancement response at 515nm when it was excited at 360nm. In the presence of Fe ion, probe 1 exhibited a detection limit of 2.10×10M. As for Al, its detection limit of 3.58×10M was significantly lower than the highest limit of Al in drinking water recommended by the WHO (7.41μM), representing a rare example in reported fluorescent probe for Al ion. The fluorescence microscopy experiments have demonstrated that probe 1 could be used in live cells for the detection of Al and Fe ions.
一种基于喹啉的荧光探针已经被制备和表征。探针 1 在 360nm 激发时，在 515nm 处表现出对 Al 和 Fe 离子的选择性传感能力，通过荧光增强响应。在 Fe 离子存在下，探针 1 表现出 2.10×10M 的检测限。对于 Al，其检测限 3.58×10M 明显低于世界卫生组织（WHO）推荐的饮用水中 Al 的最高限量（7.41μM），代表了报道的用于 Al 离子的荧光探针中的一个罕见实例。荧光显微镜实验表明，探针 1 可用于活细胞中 Al 和 Fe 离子的检测。
