We propose a new approach for the versatile sensitization of luminescent lanthanide cations. A hydrophobic chromophore is incorporated into a micellar assembly formed by the amphiphilic lanthanide chelate. The sensitizer to lanthanide energy transfer occurs between the two moieties without covalent linkage.

The narrow, near infrared (NIR) emission from lanthanide ions has attracted great interest, particularly with regard to developing tools for bioimaging, where the long lifetimes of lanthanide excited states can be exploited to address problems arising from autofluorescence and sample transparency. Despite the promise of lanthanide-based probes for near-IR imaging, few reports on their use are p...

A class of novel multifunctional hybrids assembled by lanthanide polyoxometalates, ionic liquid and lanthanide complexes were prepared through the reactions of ion exchange and coordination in mild conditions. These hybrids possess two luminescence centers, one is lanthanide polyoxometalates ([EuW10O36](9-) or [TbW10O36](9-)), the other is lanthanide complexes of 1,10-phenanthroline (phen) (or ...

Paramagnetic and variable temperature 13C and 45Sc nuclear magnetic resonance studies are performed for nitride clusterfullerenes MSc2N@C80 with icosahedral Ih(7) carbon cage, where M runs through all lanthanides forming nitride clusters. The influence of the endohedral lanthanide ions on the NMR spectral pattern is carefully followed, and dramatic differences are found in peak positions and li...

The advent of different lanthanide-binding reagents has made site-specific labelling of proteins with paramagnetic lanthanides a viable proposition. This brings many powerful techniques originally established and demonstrated for paramagnetic metalloproteins into the mainstream of structural biology. The promise is that, by exploiting the long-range effects of paramagnetism, lanthanide labellin...

Lanthanides in compounds can adopt the tetravalent [Xe]4f n−1 (like Ce4+, Pr4+, Tb4+), the trivalent [Xe]4f n (all lanthanides), or the divalent [Xe]4f n+1 configuration (like Eu2+, Yb2+, Sm2+, Tm2+). The 4f -electron binding energy depends on the charge Q of the lanthanide ion and its chemical environment A. Experimental data on three environments (i.e., the bare lanthanide ions where A = vacu...

Luminescent lanthanide chelates have unusual spectroscopic characteristics that make them valuable alternative probes to conventional organic fluorophores. However, fundamental parameters such as their quantum yield, and radiative and nonradiative decay rates have been difficult or impossible to measure. We have developed a simple and robust method based on resonance energy transfer to accurate...

Paramagnetic and variable temperature C and Sc nuclear magnetic resonance studies are performed for nitride clusterfullerenes MSc2N@C80 with icosahedral Ih(7) carbon cage, where M runs through all lanthanides forming nitride clusters. The influence of the endohedral lanthanide ions on the NMR spectral pattern is carefully followed, and dramatic differences are found in peak positions and line w...

A series of lanthanide oxide microspheres and hollow spheres have been fabricated by thermolysis of corresponding lanthanide coordination compounds formed via bottom-up self-assembly.

Luminescent lanthanide racks are formed in solution through supramolecular assembly of lanthanide ions with a rigid bis-didentate sensitiser ligand and octadentate aminopolycarboxylate ligands.
