title: A Selective Fluorescent Sensor for Hg(2+).
abstract: A novel rhodamine based fluorescent chemosensor RQP was prepared and characterized by (1)HNMR, (13)CNMR and HR-MS. The properties of RQP were studied through UV-Vis spectroscopy and fluorescence spectroscopy. RQP showed highly selectivity toward Hg(2+) over other metal ions, including Ag(+), Cd(2+), Cu(2+), Na(+), Mg(2+), Ni(2+), Pb(2+), Fe(3+), and Zn(2+) in aqueous solutions. The recognition process is reversible and confirmed by EDTA experiment.
