Stable Lanthanide Luminescence Agents Highly Emissive in Aqueous
Solution:Multidentate 2-Hydroxyisophthalamide Complexes of
Sm3+,Eu3+,Tb3+,Dy3+
正文：Applications such as high throughput assays (drug development,
genomic screening,and clinical diagnostic assays) or fluorescence
microscopy require highly sensitive detection of low concentration
analytes,with many analyses performed in a short period of time
and without preliminary purification of the sample.1-6 Fluorescence
detection is ideal for such applications.The unique electronic
properties of lanthanide cations (long luminescence lifetimes,very
sharp emission bands and,a large energy gap between the absorption
and emission bands of the complexes)7 make them ideal as
specific reporters.Long lifetimes enable temporal discrimination
through time-resolved measurements in a complex mixture.This
gives accurate and highly sensitive quantification of specific targets
by elimination of background fluorescence.Consequently,homogeneous,
time-resolved fluoroimmunoassays which primarily incorporate
Eu3+ complexes as donors have been marketed.2,8,9 However,
the sensitivity of these agents is limited by the low efficiency
of the ligand-to-lanthanide energy conversion or by insufficient
protection of the lanthanide cation from the aqueous environment
(coordination of water leads to nonradiative decay of the lanthanide
excited state).10,11 To make efficient luminescent probes,the
lanthanide complex must be both sufficiently bright and stable in
very dilute aqueous solution,a challenging combination.1,9,12
We report here a new generation of lanthanide complexes based
on 2-hydroxyisophthalamide chelating units.Two ligands,depicted
in Figure 1,have been evaluated:the macrobicycle H3L1 (whose
synthesis was described previously)13 and the octadentate ligand
H4L2.Both form luminescent and highly stable Ln complexes (Ln
) Sm,Eu,Tb,Dy) suitable for practical applications under
physiological conditions.
