Structural and Luminescent Properties of Micro- and Nanosized Particles of Lanthanide Terephthalate Coordination Polymers

Reaction in water between rare earth ions (Ln ) Y, La-Tm, except Pm) and the sodium salt of terephthalic acid leads to a family of lanthanide-based coordination polymers of general formula [Ln2(C8H4O4)3(H2O)4]n with Ln ) La-Tm or Y. The isostructurality of ...

Photoluminescent Microporous Lanthanide Silicate AV-21 Frameworks

Philip Pattison

The hydrothermal synthesis and structural characterization of the lanthanide silicate system [Na6Ln2Si12O30x H2O] (Ln=La3+, Sm3+, Eu3+, Gd3+, and Tb3+), named AV-21, has been reported. Structural elucidation of the Sm3+ analogue (isomorphous with the Eu3+, ...

What governs nitrogen configuration in substituted aminophosphines?

Matthew Wodrich, Pierre-Yves Morgantini

The trigonal planar geometry of the nitrogen atom in commonly used phosphoramidite ligands is not in line with the traditional valence shell electron pair repulsion (VSEPR) model. In this work, the effects governing nitrogen configuration in several substi ...

Stable ß-Turns of Tripeptides in Water through Cation-π Interactions

Karl Gademann

Taking a a turn. Short tripeptides that form stable ß turns in water are remarkably stable against chemical and thermal degradation. Terminal cation-π interactions lead to stabilization of these turns that are formed independently of sequence. ...

Visible-Light Excitation of Infrared Lanthanide Luminescence via Intra-Ligand Charge-Transfer State in 1,3-Diketonates Containing Push-Pull Chromophores

Rosario Scopelliti, Jean-Claude Bünzli, Frédéric Gumy

A new 1,3-diketonato ligand containing both an electron-donor [4-(dimethylamino)benzene] and an electron-acceptor (4- nitrobenzene) group and its lanthanide complexes have been prepared. They display an intense intra-ligand charge-transfer absorption trans ...

A Novel Strategy for the Design of 8-Hydroxyquinolinate- Based Lanthanide Bioprobes That Emit in the Near Infrared Range

Jean-Claude Bünzli, Caroline Vandevyver

A new polydentate tripodal ligand T2soxMe was synthesized to take advantage of the chelating effect of tridentate 8- hydroxyquinolinate subunits. Potentiometric and spectrophotometric titrations reveal seven pKa values of between 3.7 and 10.2. In water, th ...

Mécanismes d'isomérisation et d'échange de ligand de complexes octaédriques labiles de cobalt (II)

Fabrice Riblet

There are only few structural thermodynamic and kinetic studies on labile octahedral complexes available today. Octahedral paramagnetic compounds of cobalt(II) have an optimum electronic relaxation leading to NMR spectra with good resolution. Therefore, th ...
