以2-羟基-1-萘醛和2-氨基喹啉为原料，设计并合成了一种新型Al3+特异性荧光探针NQ。添加 Al3+ 后，与水溶液中其他检测的金属离子相比，NQ 的荧光强度显着增强。 Job's图的结果表明探针与Al3+之间形成了1:1的复合物，并且通过IR分析和1H NMR滴定阐明了NQ与Al3+之间系统可能的结合模式。此外，其他金属离子对Al3+的检测影响不大。 Al3+检测中NQ的检出限为1.98μM，低于世界卫生组织规定的饮用水中的水平（7.4μM）。此外，荧光探针NQ只需用适当的试剂（例如F-）处理即可回收，也可用于实际样品中Al3+的检测。
A new Al3+-specific fluorescent probe NQ was designed and synthesized from 2-hydroxy-1-naphthaldehyde and 2-aminoquinoline. Upon the addition of Al3+, the fluorescent intensity of NQ was significantly enhanced compared with other examined metal ions in aqueous solution. The result of a Job’s plot indicated the formation of a 1:1 complex between the probe and Al3+, and the possible binding mode of the system between NQ and Al3+ was clarified by IR analysis and 1H NMR titration. Moreover, other metal ions examined had little effect on the detection of Al3+. The detection limit of NQ for Al3+ detection was 1.98 μM, which is lower than the level (7.4 μM) in drinking water defined by the World Health Organization. In addition, the fluorescent probe NQ could be recyclable simply through treatment with a proper reagent such as F−, and could also be used for the detection of Al3+ in real samples.
