  Synthesis of Coumarin-Appended Pyridyl Tricarbonylrhenium(I) 2,2′-Bipyridyl Complexes with Oligoether Spacer and Their Fluorescence Resonance Energy Transfer Studies

  摘要：

  A series of rhenium(I) complexes with appended coumarin ligand has been synthesized and characterized, and their fluorescence resonance energy transfer (FRET) properties have been studied. The interaction of the complexes with metal ions was investigated by UV-vis, luminescence, and NMR spectroscopic methods. The binding of various metal ions of different sizes would cause the changes in the conformation of the molecule, leading to a change in the donor-acceptor distance and FRET efficiency.
