| Abstract: | A novel rhodamine based fluorescent chemosensor RQP was prepared and characterized by 1HNMR, 13CNMR and HR-MS. The properties of RQP were studied through UV–Vis spectroscopy and fluorescence spectroscopy. RQP showed highly selectivity toward Hg2+ over other metal ions, including Ag+, Cd2+, Cu2+, Na+, Mg2+, Ni2+, Pb2+, Fe3+, and Zn2+ in aqueous solutions. The recognition process is reversible and confirmed by EDTA experiment. |
