Fe(3+)-selective fluorescent probe based on aminoantipyrine in aqueous solution.


PMID 22982382

Abstract

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+).
