Abstract

A benzthiazole-based multifunctional chemosensor was designed with siderophores like binding sites for recognition of Fe³⁺ and both hydrogen bond donor and acceptor binding sites for oxyanion HSO₄. The sensor recognizes Fe³⁺ selectively through enhancement of fluorescence emission intensity at 440 nm and recognizes HSO₄- through a bathochromic shift in UV-vis spectra from 315 nm to 365 nm with clear isosbestic points at 345 nm and 395 nm. The recognition of both Fe³⁺ and HSO₄ is free from the interference from the other cations and anions, respectively.
