| Abstract: | Two fluorescent probes, (N1''E, N3''E)-N1'', N3''-bis((7-N,N-diethylaminocoumarin-3-yl)methylene) malonohydrazide and (N1''E, N4''E)-N1'', N4''-bis((7-N,N-diethylaminocoumarin-3-yl)methylene) succinohydrazide, bearing acylhydrazone group as binding site and coumarin group as the fluorescence signal group were synthesized and characterized by conventional techniques. These probes showed notable fluorescence turn-off response for Cu2+ over other metals ions. The probes and Cu2+ form 1:2 coordination complexes according to spectroscopy data and Job''s plots. Further study demonstrated that the detection limit of Cu2+ for the probes was as low as 10-9 mol/L. |
