Metals in Proteins: Correlation Between the Metal-Ion Type, Coordination Number and the Amino-Acid Residues Involved in the Coordination

Metal ions are constituents of many metalloproteins, in which they have either catalytic (metalloenzymes) or structural functions. In this work, the characteristics of various metals were studied (Cu, Zn, Mg, Mn, Fe, Co, Ni, Cd and Ca in proteins with know ...

Role of Inner- and Outer-Sphere Bonding in the Sensitization of EuIII-Luminescence Deciphered by Combined Analysis of Experimental Electron Density Distribution Function and Photophysical Data

Jean-Claude Bünzli

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 ...

Remarkable Tuning of the Photophysical Properties of Bifunctional Lanthanide tris(Dipicolinates) and its Consequence on the Design of Bioprobes

Jean-Claude Bünzli, Anne-Sophie Chauvin, Anne-Laure Gassner, Céline Rita Duhot

Derivatives of dipicolinic acid with a polyoxyethylene pendant arm at the pyridine 4-position have been functionalized for potential grafting with biological material. Four ligands with different terminal functions (alcohol, methoxy, phtalimide and amine) ...

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 ...

Thermodynamic Parameters Governing the Self-Assembly of Head–Head–Head Lanthanide Bimetallic Helicates

Rosario Scopelliti, Jean-Claude Bünzli, Thomas Binderup Jensen

Abstract: The heterobitopic ligands LABX (X=1,2, 3,4 or 5),diff ering only by a Cl or NEt2 substituent,have been designed to complex with a pair of lanthanide ions to form triple-stranded bimetallic helicates of overall composition [Ln2ACHTUNGTRENUNG(LABX) ...

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 ...

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 ...
