Synthesis, Structure, and Magnetic Properties of Na3LnMn3O3(AsO4)3 (Ln = La, Sm, and Gd): A New 3d-4f Series Exhibiting One-Dimensional Manganese(III) Oxide Chains Connected via LnO9 Units

In attempts to synthesize compds. contg. mixed lanthanide and transition metal oxide magnetic nanostructures, a new 3d-4f arsenate phase, Na3GdMn3O3(AsO4)3, was isolated using high-temp., molten-salt methods. The X-ray single-crystal structure anal. shows ...

Benzothiazole- and Benzoxazole-Substituted Pyridine-2-Carboxylates as Efficient Sensitizers of Europium Luminescence

Rosario Scopelliti, Jean-Claude Bünzli, Frédéric Gumy

A facile synthesis of benzothiazole- and benzoxazole-substituted pyridine-2-carboxylic acids has been developed. These ligands form mononuclear nine-coordinate complexes [Ln(κ3-ligand)2(κ1-ligand)(H2O)2] with light and heavy trivalent lanthanides, as estab ...

Luminescent Bimetallic Lanthanide Bioprobes for Cellular Imaging with Excitation in the Visible-Light Range

Jean-Claude Bünzli, Anne-Sophie Chauvin, Frédéric Gumy, Caroline Vandevyver, Bo Song

A series of homoditopic ligands H2LCX (X=4–6) has been designed to self-assemble with lanthanide ions (LnIII), resulting in neutral bimetallic helicates of overall composition [Ln2ACHTUNGTRENUNG(LCX)3] with the aim of testing the influence of substituents ...

Tuning the self-assembly of lanthanide triple stranded heterobimetallic helicates by ligand design

Rosario Scopelliti, Jean-Claude Bünzli, Thomas Binderup Jensen

The heterobitopic ligands LAB4 and LAB5 have been designed and synthesised with the ultimate aim of self-assembling dual-function lanthanide complexes containing either a magnetic and a luminescent probe or two luminescent probes emitting at different wave ...

Luminescent lanthanides bioprobes emitting in the visible and/or near-infrared ranges

Steve Comby

This Ph.D. work deals with the development of lanthanide-based bioprobes for biomedical analyses and imaging. For this purpose, two different approaches have been followed, one focusing on visible-emitting complexes, while the second addresses the sensitiz ...

Acetonitrile exchange kinetics on di- and trivalent lanthanide ions

Gabriella Eva Bodizs

The knowledge and understanding of the mechanism as well as the rate constant of the solvent exchange reactions are fundamental, since these reactions represent an important step in complex formation reactions on metal ions. Solvent exchange reactions in a ...

Near-Infrared Luminescence of Nine-Coordinate Neodymium Complexes with Benzimidazole-Substituted 8-Hydroxyquinolines

Rosario Scopelliti, Jean-Claude Bünzli, Frédéric Gumy

A new class of benzimidazole-substituted 8-hydroxyquinoline ligands has been prepared that contain a monoanionic tridentate N,N,O-coordinating unit. These ligands form charge-neutral lanthanide complexes of the type [Ln(LR) 3] · nH2O or [Ln2(L2)3] · nH2O ( ...
