title: A Fast-Responsive Fluorescent Sensor for Hg(2+) with High Selectivity and Sensitivity in Aqueous Media.
abstract: A fast-responsive fluorescent phenylamine-oligothiophene sensor 2TBDA was reported. This sensor exhibited highly selective and sensitive detection of Hg(2+) ion in THF/H2O (7/3, v/v) solution through fluorescence quenching. The detection was not affected by the coexistence of other competitive metal ions. In addition, the detection limit was found to be as low as 3.841 × 10(-7) M.
