A novel and simple Schiff base composed with 9-anthraldehyde and 4-aminoantipyrine was synthesized and characterized as a fluorescent probe. In the presence of Fe(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 Fe(3+), and the possible binding mode of the system was also proposed. Moreover, other examined metal ions had no effect on the detection of Fe(3+).
一种新型的简单席夫碱，由 9-蒽醛和 4-氨基安替比林组成，被合成并被表征为一种荧光探针。在存在 Fe(3+)的情况下，该探针在水溶液中对其他检查的金属离子具有显著增强的荧光强度。Job 的绘图方法表明，探针与 Fe(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，其他检查的金属离子对 Fe(3+)的检测没有影响。
