Résumé

Efficient lanthanide (Ln) luminescent probes require good ligand-to-metal energy transfer and high aqueous stability. A family of ligands based on 2-hydroxyisophthalamide chelating units is reported. These form highly stable, eight-coordinate Ln complexes. Several of these (Ln = Sm, Eu, Tb, Dy) emit in the visible region with good ligand-to-lanthanide energy transfer. The absolute quantum yields of the two Tb complexes studies (Phi = 0.59, 0.61) and high absorbance make these the brightest luminescent probes for time-resolved detection; the emission spectrum of one complex can be seen down to 10-15 M. The low overlap of the four different Ln complexes enables their simultaneous detection and discrimination.
