摘要：After functionalization, a new epindolidion derivative bearing a vinyl group was synthesized as a naked eye fluorescent probe for Hg2+ through two steps. The probe showed good selectivity to Hg2+ over other metal cations in CH3CN. On the basis of the addition of Hg2+, the fluorescence emission of the probe at 485 nm was ratio quenched along with the appearance of the new peak at 574 nm. Simultaneously, the absorbance of the probe showed bathochromic shift as a function of the increasing concentration of Hg2+. All of the features mentioned make this compound a useful probe for Hg2+ measurement. To the best of our knowledge, it's the first fluorescent probe based on epindolidion. (C) 2016 Elsevier Ltd.
