A Schiff base compound derived from naphthalene has been synthesized and characterized as an Al3+ -selective fluorescent probe. The chemosensor (L) exhibits high selectively for Al3+ in aqueous solution, even in the presence of biologically relevant cations such as Na+ , K+ , Ca2+ , Mg2+ , Pb2+ and several transition metal ions. There was no observed interference from anions like Br- , Cl- , HSO3- , SO32- , S2 O32- , NO2- , CO32- and AC- . The lowest detection limit for the chemosensor L was found to be 1.89 × 10-8 M with a linear response towards Al3+ over a concentration range of 5 × 10-6 to 4 × 10-5 M. Furthermore, the proposed chemosensor has been used for imaging of Al3+ in two different types of cells with satisfying results, which further demonstrates its value for practical application in biological systems.
