Three ethanedithiol-linked bisquinoline derivatives with a different number of methoxy substituents on the aromatic ring exhibit a significant fluorescent responsetoward mercury(II) and iron(III) ions. Fluorescence enhancement (OFF–ON), ratiometric and fluorescence quenching (ON–OFF) responses were achieved with the same molecular skeleton, by changing the methoxy substitution pattern.
