Lighting up for iodide: A fluorescence turn-on sensor for iodide has been developed based on a luminescence quenching and recovery strategy. An anthracene–thymine dyad was synthesized that formed a complex with a mercury(II) ion, which led to fluorescence quenching of the anthracene; the iodide anion extracts the mercury(II) ion from the complex and restores the fluorescence of the anthracene (see scheme).
