Yanmei Zhou et al.
Spectrochimica acta. Part A, Molecular and biomolecular spectroscopy, 98, 14-17 (2012-09-18)
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
