A Factor Two Improvement in High-Field Dynamic Nuclear Polarization from Gd(III) Complexes by Design

David Lyndon Emsley, Marinella Mazzanti, Anne-Sophie Chauvin, Dominik Józef Kubicki, Gabriele Stevanato, Georges Guévork Jean-Jacques Menzildjian

Gadolinium(III) complexes have recently been demonstrated to have potential as polarizing agents for high-field dynamic nuclear polarization (DNP) NMR spectroscopy. By tailoring the ligand design to reduce the zero-field splitting (ZFS), we demonstrate a q ...

Synthesis and Characterization of a Water Stable Uranyl(V) Complex

Rosario Scopelliti, Radmila Faizova, Marinella Mazzanti, Anne-Sophie Chauvin

We have identified a polydentate aminocarboxylate ligand that stabilizes uranyl(V) in water. The mononuclear [UO2(dpaea)]X, (dpaeaH2 = Bis(pyridyl-6-methyl-2-carboxylate)-ethylamine; X = CoCp2*+ or X = K(2.2.2.cryptand) complexes have been isolated from an ...

Self-Assembled Nanomicelles as MRI Blood-Pool Contrast Agent

Lothar Helm, Anne-Sophie Chauvin, Vassily Vorobiev

Gadolinium‐loaded nanomicelles show promise as future magnetic resonance imaging (MRI) contrast agents (CAs). Their increased size and high gadolinium (Gd) loading gives them an edge in proton relaxivity over smaller molecular Gd‐complexes. Their size and ...

Carbazole as Linker for Dinuclear Gadolinium-Based MRI Contrast Agents

Lothar Helm, Bibimaryam Mousavi, Anne-Sophie Chauvin, Loïck Moriggi

Ligands able to complex two gadolinium ions have been synthesized and characterized in view of the ability of the complexes to increase the spin relaxation of water protons. All ligands are based on the heptadentate diethylenetriaminetetraacetic acid (DTTA ...

A New Anti-Counterfeiting Feature Relying on Invisible Luminescent Full Color Images Printed with Lanthanide-Based Inks

Roger Hersch, Jacques-Edouard Moser, Anne-Sophie Chauvin, Julien Alexandre Andres

Europium and terbium trisdipicolinate complexes are inkjet printed onto paper with commercially available desktop inkjet printers. Together with a commercial blue luminescent ink, the red-emitting luminescent ink containing europium and the green-emitting ...

New sensitizers for dye-sensitized solar cells featuring a carbon-bridged phenylenevinylene

Michael Graetzel, Anne-Sophie Chauvin, Aswani Yella

We demonstrate that a carbon-bridged phenylenevinylene (CPV)-linked dye serves as a novel and efficient sensitizer for dye-sensitized solar cells. The cells show IPCE values of greater than 90%, PCEs of up to 7.12%, and high open circuit voltages reaching ...

Synthesis and cell localization of self-assembled dinuclear lanthanide bioprobes

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

Lanthanide bioprobes and bioconjugates are ideal luminescent stains in view of their low propensity to photobleaching, sharp emission lines and long excited state lifetimes permitting time-resolved detection for enhanced sensitivity. In this paper, we expa ...

Energy transfer in coumarin-sensitised lanthanide luminescence: investigation of the nature of the sensitiser and its distance to the lanthanide ion

Anne-Sophie Chauvin, Julien Alexandre Andres

A series of lanthanide complexes Ln(dpxCy)(3) have been synthesised. The ligands are composed of a coordinating dipicolinic acid backbone decorated with a polyoxyethylene arm fitted with a coumarin moiety at its extremity. The nature of the coumarin ...
