Abstract

A novel l-nitrobenzaldebyde appended rhodamlne-based cbemosensor (L) for selective detection of Al³⁺ions has been synthesized and characterized by various spectroscopic techniques. The chemosensor L showed high sensitivity towards Al³⁺ions without interference from other bioiogically significant cations examined in CH₃CN/H₂O (8: 2, v/v) media by changing the color from colorless to deep pink which was very easily observed by naked eye. While other metal ions, alkali metal and alkaline earth metal cations did not induce such a change. The 1: 1 binding stoichiometry of the metal complex was established by UV-Vis spectroscopy.
