The development of the brightest luminescent europium(III) complexes is traced, including analysis of the C3-symmetric core complex based on a functionalized triazacyclononane and identification of the most suitable strongly absorbing chromophore. St... Read More about EuroTracker® dyes : design, synthesis, structure and photophysical properties of very bright europium complexes and their use in bioassays and cellular optical imaging.

Catalytic SNAr of unactivated aryl chlorides (2014)
Journal Article

We present nucleophilic aromatic substitution of unsubstituted aryl chlorides via a mechanism that is catalytic in [CpRu(p-cymene)]PF6 and involves a Ru(η6-arylchloride) intermediate. From the spectroscopic evidence we infer that arene exchange is th... Read More about Catalytic SNAr of unactivated aryl chlorides.

Comparative analysis of conjugated alkynyl chromophore-triazacyclononane ligands for sensitized emission of europium and terbium (2014)
Journal Article
Soulié, M., Latzko, F., Bourrier, E., Placide, V., Butler, S. J., Pal, R., …Maury, O. (2014). Comparative analysis of conjugated alkynyl chromophore-triazacyclononane ligands for sensitized emission of europium and terbium. Chemistry - A European Journal, 20(28), 8636 -8646. https://doi.org/10.1002/chem.201402415

A series of europium and terbium complexes based on a functionalized triazacyclononane carboxylate or phosphinate macrocyclic ligand is described. The influence of the anionic group, that is, carboxylate, methylphosphinate, or phenylphosphinate, on t...

Emissive europium complexes that stain the cell walls of healthy plant cells, pollen tubes and roots (2014)
Journal Article
Palmer, A. J., Ford, S. H., Butler, S. J., Hawkins, T. J., Hussey, P. J., Pal, R., …Parker, D. (2014). Emissive europium complexes that stain the cell walls of healthy plant cells, pollen tubes and roots. RSC Advances, 4(18), 9356-9366. https://doi.org/10.1039/c3ra45426f

The cell-staining behaviour of a set of five emissive europium complexes has been studied in Nicotiana tabacum BY-2 cells and pollen tubes, Nicotiana benthamiana plant leaves and in the root hairs of the wild-type plant Arabidopsis thaliana (Columbia...
