Luminescent Benzothiazole-Based Fluorophore of Anisidine Scaffoldings: a "Turn-On" Fluorescent Probe for Al³⁺ and Hg²⁺ Ions.

Gargi Dhaka¹, Navneet Kaur², Jasvinder Singh¹.

Abstract

A new anisidine possessing benzothiaozle-based chemosensor (1) has been designed and synthesized. The chemosensor 1 was designed to provide hard base environment for ratiometric detection of comparatively less studied Al3+ ions. In CH3CN, the fluorescence spectra of chemosensor 1 red shifted from 368 to 430 nm with addition of Al3+ and Hg2+ ions; while Cu2+ ions caused quenching of emission intensity of 1. These differential changes observed with Al3+ and Cu2+ ions addition enabled chemosensor 1 to construct "NOR" and "TRANSFER" logic gates.
