Abstract:
The novel 8-Aminoquinoline(8-AQ) derivatives receptor was designed and synthesized.Its struc ture was characterized by NMR and ESI-MS.It was investigated to recognize metal ions such as Cu~(2+), Hg~(2+), Pb~(2+), Zn~(2+), Ni~(2+) and Cd~(2+) via its absorption and fluorescence spectra.The recognition mechanism .and bind ing mode were discussed.The results showed that 8-AQ derivatives 1 coordinated with Cu~(2+) can induce a new absorption peak at 509 nm, which turned the solution to red from colorless.In acetonitrile Hg~(2+) and Cu~(2+) induced dramatic enhancement in the fluorescence of the derivation 1 by 368 and 192 folds.Job plot showed 1:1 stoichiometry between 8-AQ and Cu~(2+) or Hg~(2+).
