  摘要：

  Two novel macrocyclic chelators L-1 and L-2 incorporating an intracyclic pyridine or 2,2'-bipyridine unit and a triethylenetetraminetetraacetic acid core (TITA) were synthesized with the aim of forming lanthanide complexes suitable as efficient long-lived luminophores. For this goal, an efficient methodology for the preparation of TITA derivatives using prealkylated precursors is described Starting from commercially available compounds, the target ligands were obtained in seven (L-1) and nine (L-2) steps in 40% and 20% overall yields. respectively. Stable Tb(III) complexes were prepared and displayed interesting luminescence properties. (C) 2009 Elsevier Ltd All rights reserved

  A series of five new 15-, 18- or 21-membered polyazamacrocycles (L-1-L-5) based on a pyridine, bipyridine or terpyridine unit and a triethylenetetraminetetraacetic acid (TTTA) skeleton is described. In ligands L-4 and L-5 the azaheterocycle contains an additional extracyclic functionality (ester group) suitable for covalently attachment to bioactive molecules. The synthetic procedure is based on the use of a linear tetra-N-alkylated tetramine synthon incorporating masked acetate arms and an efficient metal template ion effect, which controls the crucial macrocyclization step. In the case of L-1-L-3, the formation of lanthanide complexes with europium(III) and terbium(III) was investigated and the fluorescence characteristics of the complexes were established. In this series, the terbium(III) complex derived from the bipyridine ligand exhibits the highest lifetime and quantum yield values (tau=2.18 ms, Phi=26%). (C) 2010 Elsevier Ltd. All rights reserved.
