Local, element-specific and time-resolved dissolution processes on a Mg–Y–RE alloy – Influence of inorganic species and buffering systems

Christian Ludwig, Andrea Ulrich, Noémie Elise Ott

The effect of body fluids inorganic species on element-specific dissolution of a Mg-Y-Rare earth elements (RE) alloy was investigated by flow microcapillary plasma mass spectrometry. A new important aspect of this method is the online monitoring of precipi ...

Lanthanide Complexes Formed with the Tri- and Tetraacetate Derivatives of Bis(aminomethyl)phosphinic Acid: Equilibrium, Kinetic and NMR Spectroscopic Studies

Laurent Quebatte, André Merbach, Eva Jakab Toth

The lanthanide(III) complexes formed with the tri- and tetraacetate derivatives of bis(aminomethyl)phosphinic acid, L1 and L2, respectively, have been studied by pH potentiometry, spectrophotometry and 1H and 17O NMR spectroscopy. L1 forms [Ln(L1)], [Ln(L1 ...

The luminescence of NaxEu3+(2−x)/3MoO4 scheelites depends on the number of Eu-clusters occurring in their incommensurately modulated structure

Jean-Claude Bünzli, Gervais Chapuis, Alla Arakcheeva, Philip Pattison, Dmitry Logvinovich, Svetlana Eliseeva

Scheelite related compounds with general formula Mn(XO4)m are of interest owing to their optical properties, stability and relatively simple preparation. Eu3+-containing scheelites are considered as red emitting phosphors and the main factors affecting the ...

Uranyl complexes formed with a para-t-butylcalix[4]arene bearing phosphinoyl pendant arms on the lower rim. Solid and solution studies

Jean-Claude Bünzli

The current interest in functionalized calixarenes with phosphorylated pendant arms resides in their coordination ability towards f elements and capability towards actinide/rare earth separation. Uranyl cation forms 1: 1 and 1: 2 (M : L) complexes with a t ...

5f-Element complexes with a p-tert-butylcalix[4]arene bearing phosphinoyl pendant arms: Separation from rare earths and structural studies

Jean-Claude Bünzli, Rosario Scopelliti

Phosphinoylated calixarenes feature high coordination ability toward f elements and a great potentiality toward actinide/rare earth separation. Here, we report three characteristic properties of a tetra-phosphinoylated p-tert-butylcalix[4]arene, B(4)bL(4) ...

Europium Complexes of Tris(dipicolinato) Derivatives Coupled to Methylumbelliferone: A Double Sensitization

Anne-Sophie Chauvin, Julien Alexandre Andres

A para-poly(oxyethylene) dipicolinic acid derivative coupled to methylumbelliferone was synthesized and used as a ligand for coordination with europium ions. Characterization of the complex by mass spectrometry and spectrophotometry was performed in aqueou ...

N-Aryl Chromophore Ligands for Bright Europium Luminescence

Jean-Claude Bünzli, Rosario Scopelliti, Svetlana Eliseeva

Sterically hindered N-aryl-benzimidazole pyridine-2-carboxylic acids (aryl = phenyl, 4-biphenyl, 2-naphthyl) readily form homoleptic, neutral, nine-coordinate europium complexes which display efficient sensitized luminescence in solid state and in dichloro ...

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

Jean-Claude Bünzli, Rosario Scopelliti, 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 ...
