  Flavonol based ruthenium acetylides as fluorescent chemosensors for lead ions

  摘要：

  Flavonol based alkynyl ruthenium complexes devoted to the detection of metal traces in solution are described. The sensitivity of both absorption and emission properties of the 3-hydroxyflavone unit as a receptor for the metal cations, and of an alkynyl ruthenium moiety as an extended pi-conjugated system, provides an efficient molecular sensor for rapid, sensitive and selective detection of lead(II) cations.

  Platinum-ethynylflavone complexes featuring various polyether arms display 3IL phosphorescence associated with the appended flavone perturbed by the platinum centre (tau approximately 20 micros), but switch dramatically to flavone-localised 1IL fluorescence (tau approximately 2 ns) upon selective binding of Pb2+.
