2-[3-(2-Aminoethylsulfanyl)propylsulfanyl]ethanamine Bearing Dansyl Subunits: An Efficient, Simple, and Rapid Fluorometric Sensor for the Detection of Mercury(II) Ions

A novel fluorometric sensor possessing two dansyl moieties based on 2-[3-(2-aminoethylsulfanyl)propylsulfanyl]ethanamine 1 was prepared by a wady synthetic approach using a conventional two-step synthesis I exhibits highly sensitive and selective on-off Hg2+ fluorescence quenching behavior in aqueou...

Summary:A novel fluorometric sensor possessing two dansyl moieties based on 2-[3-(2-aminoethylsulfanyl)propylsulfanyl]ethanamine 1 was prepared by a wady synthetic approach using a conventional two-step synthesis I exhibits highly sensitive and selective on-off Hg2+ fluorescence quenching behavior in aqueous acetonitrile solutions and is shown to discriminate various competing metal ions such as Cu2+, Ag+, Ca2+, Mn2+, Zn2+, Ba2+, Cd2+, Co2+, Na+, and K+ exhibiting a detection limit of 7 nM or 1.4 ppb with a working range of 1.8-15 ppb
