摘要： Herein, a novel chemodosimeter with 1-(2-aminoethyl)-3-phenylthiourea as MeHg+ or Hg2+ reacting group linked via its N atom at position 3 to boron dipyrromethene (Bodipy-1) have been synthesized, which exhibits longer excitation wavelength, selective and sensitive colorimetric and fluorimetric response toward methylmercury (MeHg+) or mercury (Hg2+) in natural media via desulfurization and intramolecular cyclization with a broad pH range from 6-10. It shows low cytotoxicity and excellent membrane permeability towards living cells, which was successfully applied to detect and image intracellular methylmercury or mercury effectively by confocal fluorescence imaging.
