摘要
A novel rhodamine based fluorescent chemosensor RQP was prepared and characterized by (HNMR)-H-1, (CNMR)-C-13 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.
