摘要
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 Al3+, 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 Al3+, and the possible binding mode of the system was also proposed. Moreover, other examined metal ions had no effect on the detection of Al3+.
