A novel fluorescent probe for gold ions (Au3+/Au+) is reported through blocking photoinduced electron transfer, in which a boron dipyrromethene (Bodipy) derivative reveals high selectivity and sensitivity in a gold-catalyzed intramolecular hydroamination, and is successfully applied to fluorescence imaging of Au3+ in living cells.
