Abstract

Abstract: A Schiff base compound derived from naphthalene has been synthesized and characterized as an Al 3+ ‐selective fluorescent probe. The chemosensor (L ) exhibits high selectively for Al 3+ in aqueous solution, even in the presence of biologically relevant cations such as Na +, K +, Ca 2+, Mg 2+, Pb 2+ and several transition metal ions. There was no observed interference from anions like Br −, Cl −, HSO3 −, SO3 2−, S2 O3 2−, NO2 −, CO3 2− and AC − . The lowest detection limit for the chemosensor L was found to be 1.89 × 10 −8 M with a linear response towards Al 3+ over a concentration range of 5 × 10 −6 to 4 × 10 −5 M. Furthermore, the proposed chemosensor has been used for imaging of Al 3+ in two different types of cells with satisfying results, which further demonstrates its value for practical application in biological systems.
