Selective sensing of Zn(II) ion by a simple anthracene-based tripodal chemosensor

A new and an easy-to-make simple tripodal shaped chemosensor 1, comprising an anthracene moiety as a fluorophore and amide, alcohol functionalities as ligating groups has been designed and synthesized for Zn(II). In CH3CN containing 0.1% DMSO, upon excitation at 370 nm, the chemosensor 1 exhibited an emission at 412 nm, which increased to a large extent upon complexation of Zn(II). Among the other metal ions examined in the study, Cd2+ moderately perturbed the emission of 1 under similar conditions.
