Abstract

A quinoline-based cation sensor shows turn-off fluorescent behavior in the presence of Hg2+, Fe3+ and Cu2+ over other cations and offers discrimination of these cations from each other on the basis of the extent of quenching. The observed electronic absorption perturbations are in good agreement with theoretical (DFT, TD-DFT) calculations.
