A novel BODIPY-RhB ratiometric fluorescent probe 1 for Hg2+ based on a fluorescence resonance energy transfer mechanism has been developed. In this system, the energy transfer efficiency is 94.8%. The BODIPY-RhB probe 1 can detect Hg2+ ions with a very low detection limit of 1.56 ppb, and very high selectivity toward Hg2+ ions. (C) 2016 Elsevier Ltd. All rights reserved.
