Non-Cytotoxic, Bifunctional EuIII and TbIII Luminescent Macrocyclic Complexes for Luminescence Resonant Energy- Transfer Experiments

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

A new macrocyclic ligand,

L^3

, has been synthesised, based on the cyclen framework grafted with three phenacyl light-harvesting groups and a C5-alkyl chain bearing a carboxylic acid function as a potential linker for biological material. Acidity constant ...

Selective Self-Assembly of Hexameric Homo- and Heteropolymetallic Lanthanide Wheels: Synthesis, Structure, and Photophysical Studies

Jean-Claude Bünzli, Marinella Mazzanti

A rational approach to the formation of pure heteropolymetallic lanthanide complexes that uses a two-step assembly strategy and exploits the different size requirements of the two metals included in the final structure is described. The investigation of th ...

pKa Estimation of Ruthenium(II)-Arene PTA Complexes and their Hydrolysis Products via a DFT/Continuum Electrostatics Approach

Paul Joseph Dyson, Ursula Röthlisberger, Christian Gossens, Antoine Dorcier

A combined d. functional theory/continuum electrostatics approach was used to est. the pKa values of metal-based compds. and their hydrolysis products. Specifically, the protonation states and abs. pKa values of [M(h6-arene)(X)(Y)(pta)]n+ (M = Ru or Os; ar ...

Self-assembly of organometallic macrocycles and cages

Thomas Brasey

Neutral metallamacrocycles with four or ten metal centers were obtained by reaction of [(R3P)PdCl2]2 with 2,3-dihydroxypyridine and derivatives or 2-hydroxynicotinic acid in the presence of base. In all these assemblies, the two O-donor atoms of the ligand ...

Stable 8-hydroxyquinolinate-based podates as efficient sensitizers of lanthanide near-infrared luminescence

Jean-Claude Bünzli, Anne-Sophie Chauvin, Steve Comby

New polydentate ligands (e.g., Tsox and TsoxMe) have been synthesized to take advantage of the chelating effect of bidentate 8-hydroxyquinolinate subunits connected to a N,N,N¢,N¢-tetraaminopropyl-1,2-ethylenediamine framework and with the aim of sensitizi ...

Supramolecular chemistry of 12-Metallacrown-3 complexes

Zacharias Immanuel Grote

12-Metallacrown-3 complexes were formed by self-assembly of organometallic half-sandwich complexes [(π-ligand)MCl2]2 (M = Ru, Rh, Ir) and 3-hydroxy-2-pyridone ligands in the presence of Cs2CO3 as base. Upon mixing of different macrocycles, reversible metal ...

Lanthanide Triple-Stranded Helicates: Controlling the Yield of the Heterobimetallic Species

Rosario Scopelliti, Jean-Claude Bünzli, Thomas Binderup Jensen

Two unsymmetrical ditopic hexadentate ligands designed for the simultaneous recognition of two different trivalent lanthanide ions have been synthesized, LAB2 and LAB3, where A represents a tridentate benzimidazole-pyridinebenzimidazole coordination unit, ...

Coordination chemistry of a new rigid, hexadentate bispidine-based bis(amine)tetrakis(pyridine) ligand

Gabor Laurenczy

The hexadentate bispidine-based ligand 2,4-bis(2-pyridyl)-3,7-bis(2-methylenepyridine)-3,7-diazabicyclo[3.3.1]nonane-9-on-1,5-bis(carbonic acid methyl ester), L-6m, with four pyridine and two tertiary amine donors, based on a very rigid diazaadamantane-der ...

Low-dimensional supramolecular architectures at metal surfaces

Sebastian Stepanow

This thesis is concerned with supramolecular architectures assembled at metal surfaces. The investigations pursued two objectives. On the one hand, the focus was placed on the fabrication of low-dimensional surface-supported network structures by applying ...

The water-soluble cluster cation [H3Ru3(C6H6)(C6Me6)(2)(O)](+): Improved synthesis, aerobic oxidation, electrochemical properties and ligand exchange studies

Gabor Laurenczy

The synthesis of the trinuclear cluster cation H3RU3(C6H6)(C6Me6)(2)(O) (1) has been considerably improved by changes in the NaBH4 addition step and by introducing chromatographic methods; in addition, the redox and ligand exchange properties of 1 hav ...
