A series of lanthanide adducts with different amounts of 1,10-phenanthroline, chloride ions, and water molecules in the inner and outer coordination spheres are investigated with the aim of relating the chemical bonding pattern in the crystals to the lumin ...
The new homoditopic ligand H2LC2′ self-assembles with lanthanide ions (LnIII) to yield neutral bimetallic helicates of overall composition [Ln2(LC2′)3]; it is fitted with two hexakis(oxyethylene) chains to test their effects on the thermo ...
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 ...
Standard theta-2 theta and pole figure X-ray diffraction techniques were used to study structural properties and preferred orientation of nanostructured TiAIN thin films prepared using cathodic are deposition. Systematic collection of reflections from latt ...
This overview presents recent work on the coordination chemistry and catalytic activity of bis-phosphine ruthenium(II)-arene complexes, RuCl(PPh3)(PR3)(eta(6)-arene), carried out in the Laboratory of Organometallic and Medicinal Chemistry at the EPFL. ...
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 ...
Here we present a comparative analysis of two types of equally monodisperse gold nanoparticles (similar to 8 nm in diameter), one coated only with dodecanethiol ligands and the other coated with a mixture of dodecanethiol and 4-methylbenzenethiol ligands. ...
Nuclear magnetic relaxation in the presence of paramagnetic centres has gained increasing interest in recent years partly due to its importance for contrast agents in magnetic resonance imaging. Rational design of new more efficient agents is possible as a ...
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 ( ...
A combination of immiscible molecules in the ligand shell of a gold nanoparticle (NP) has been shown to phase separate into a rippled structure; this phase separation can be used to direct the assembly of the NPs into chains. Here we demonstrate that only ...
