Synthesis and characterization of partially substituted at lower rim phosphorus containing calix(4)arenes

Rosario Scopelliti, Anne-Sophie Chauvin

The synthesis and characterization of several new phosphorus-containing partially lower rim substituted derivatives of 5,11,17,23-tetra(t-butyl) calix(4)arene (1) and 5,11,17,23-tetra(t-octyl)calix(4)arene (II), namely 5,11,17,23-tetra(t-butyl)-25,27-dihyd ...

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

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

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 ...

Luminescent lanthanide bimetallic triple-stranded helicates as potential cellular imaging probes

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

Water-soluble triple-stranded [Ln2(L)3] helicates have been successfully tested as imaging probes in human cervical adenocarcinoma cells (HeLa), the complex being not toxic and clearly staining their cytoplasm in a concentrationdependent manner. ...

Use of Dipicolinate-Based Complexes for Producing Ion-Imprinted Polystyrene Resins for the Extraction of Yttrium-90 and Heavy Lanthanide Cations

François Bochud, Jean-Claude Bünzli, Rosario Scopelliti, Anne-Sophie Chauvin

Highly selective separation of yttrium (and lanthanides) is of interest for the design of radiopharmaceuticals, and an efficient method based on the ion-imprinting concept is proposed here. The synthesis and structural, thermodynamic and photophysical char ...

Fluorinated β-Diketones for the Extraction of Lanthanide Ions: Photophysical Properties and Hydration Numbers of Their EuIII Complexes

Jean-Claude Bünzli, Frédéric Gumy, Anne-Sophie Chauvin

Tris(β-diketonato)europium(III) with a series of variably fluorinated ligands derived from 3,5-heptanedione were synthesised with the aim of determining their hydration state under extraction conditions. The number of coordinated water molecules was determ ...

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

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

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 ...

Lanthanide 8-hydroxyquinoline-based podates with efficient emission in the NIR range

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

The novel hydroxyquinoline-containing tetrapodal ligand forms water soluble and stable chelates and is a good sensitizer of the NIR luminescence of its NdIII and YbIII complexes; its easy synthesis opens the way for potential biomedical applications. ...
