A novel and simple Schiff base based on 2-pyridine formaldehyde and 4-aminoantipyrine was synthesized and characterized as a fluorescent probe. In the presence of Al(3+), the fluorescent intensity has a dramatic enhancement over other examined metal ions in aqueous solution. The method of Job's plot indicated the formation of 1:1 complex between probe and Al(3+), and the possible binding mode of the system was also proposed. Moreover, other examined metal ions had no effect on the detection of Al(3+).
合成了一种基于 2-吡啶甲醛和 4-氨基安替比林的新型简单席夫碱，并将其作为荧光探针进行了表征。在存在 Al(3+)的情况下，该荧光探针在水溶液中对其他检测金属离子的荧光强度有显著增强。Job 点法表明探针与 Al(3+)之间形成了 1:1 的配合物，并且还提出了该体系的可能结合模式。此外，其他检测金属离子对 Al(3+)的检测没有影响。
