A novel boron-dipyrromethene (BODIPY) based fluorescence turn-on sensor for detecting Fe3+ in aqueous media is reported with 23-fold fluorescence enhancement. The sensor is comprised of a combination of BODIPY fluorophore and a new Fe3+-recognizing cryptand that exhibits high selectivity, sensitivity, and reversibility toward Fe3+ detection. Cell imaging studies demonstrate that this sensor is capable of sensing Fe3+ in living cells.
