| Abstract: | 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?, S2O32?, 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. |
