  Lanthanide complexes of new polyaminocarboxylates with the bis-pyrazolylpyrimidine chromophore

  摘要：

  We describe the straightforward synthesis of a new polyacid ligand derived from the bis-pyrazolyipyrimidine motif that displayed excellent properties concerning its ability to sensitize the emission of lanthanides. Emission lifetimes were in the range of ms and quantum yields were 0.15 and 0.85 for Eu and Tb, respectively, among the largest measured by us in related compounds, thus making this ligand an excellent candidate for its application in multitagging time-resolved fluoroimmunoassays.

  Some B–B linked ‘back-to-back’ bis[tris(pyrazolyl)borate] bridging ligands [(Rpz)3B–B(Rpz)3] (where Rpz is 3-R-pyrazolyl) have been prepared: when R=H or Me the ligands have two terdentate compartments, and have been used to prepare a variety of molybdenum complexes; when R=2-pyridyl, the ligand has two B–B linked hexadentate cavities which each bond a lanthanide(III) ion.
