Light-driven Au(III)-promoted cleavage of triazole-bearing amine derivatives and its application in the detection of ionic gold.

Light-driven Au(III)-promoted oxidative cleavage of triazole-bearing amine derivatives is utilized for the detection of ionic gold in aqueous media. A bistriazole-bearing boron dipyrromethane (1(BODIPY)) exhibited selective and sensitive fluorescence enhancement by the addition of Au(3+) and subsequent UV irradiation.
