Influence of Symmetry on the Luminescence and Radiative Lifetime of Nine-Coordinate Europium Complexes

Rosario Scopelliti, Jean-Claude Bünzli, Svetlana Eliseeva

Homoleptic mononuclear nine-coordinate lanthanum(III) and europium(III) tris-complexes [Ln(N^N^O)3]·nH2O with two tridentate N-benzyl-benzimidazole pyridine-2-carboxylates exhibit a rare C3-symmetry of the lanthanide coordination polyhedron in the solid st ...

On the design of highly luminescent lanthanide complexes

Jean-Claude Bünzli

Presently, phosphors and luminescent materials for lighting, telecommunications, displays, security inks and marking, as well as for probes in biosciences represent one third of the total value of the lanthanides used worldwide. If optical glasses and lase ...

Stereocontrolled Self-Assembly and Self-Sorting of Luminescent Europium Tetrahedral Cages

Jean-Claude Bünzli

Coordination-directed self-assembly has become a well-established technique for the construction of functional supramolecular structures. In contrast to the most often exploited transition metals, trivalent lanthanides Ln(III) have been less utilized in th ...

A Eu(III) Tetrakis(b-diketonate) Dimeric Complex: Photophysical Properties, Structural Elucidation by Sparkle/AM1 Calculations, and Doping into PMMA Films and Nanowires

Rosario Scopelliti, Jean-Claude Bünzli

Reaction of Ln(III) with a tetrakis(diketone) ligand H4L [1,1?-(4,4?-(2,2-bis((4-(4,4,4-trifluoro-3-oxobutanoyl) phenoxy)methyl)propane-1,3-diyl)bis(oxy)bis(4,1-phenylene))bis(4,4,4-trifluorobutane-1,3-dione)] gives new podates which, according to mass spe ...

Lanthanide coordination chemistry: from old concepts to coordination polymers

Jean-Claude Bünzli

Because of their remarkable and unmatched optical and magnetic properties, the lanthanides are under the limelight when it comes to high technology. These elements are used in strategic applications such as optical glasses and lasers, telecommunications, l ...

Tridentate Benzimidazole-Pyridine-Tetrazolates as Sensitizers of Europium Luminescence

Rosario Scopelliti, Jean-Claude Bünzli, Svetlana Eliseeva

We report on new anionic tridentate benzimidazole-pyridine-tetrazolate ligands that form neutral 3:1 complexes with trivalent lanthanides. The ligands are UV-absorbing chromophores that sensitize the red luminescence of europium with energy-transfer effici ...

Lighting up cells with lanthanide self-assembled helicates

Jean-Claude Bünzli

Lanthanide bioprobes and bioconjugates are ideal luminescent stains in view of their low propensity to photobleaching, sharp emission lines and long excited state lifetimes permitting time-resolved detection for enhanced sensitivity. We show here how the i ...

Lanthanide(III) dendrimer complexes based on diphenylquinoxaline derivatives for photonic amplification

Jean-Claude Bünzli

A series of novel lanthanide(III) complexes (Ln=Gd, Er, Yb) based on dendritic diphenylquinoxaline (DPQ) ligands was designed and synthesized with the aim of enhancing the luminescence intensity of Er3+ and Yb3+ ions for photonic applications. The diphenyl ...

Brilliant Photoluminescence and Triboluminescence from Ternary Complexes of Dy-III and Tb-III with 3-Phenyl-4-propanoy1-5-isoxazolonate and a Bidentate Phosphine Oxide Coligand

Rosario Scopelliti, Jean-Claude Bünzli

Three new lanthanide heterocyclic beta-diketonate complexes [Dy(PPI)(3)(EtOH)(2)] (1), [Dy(PPI)(3)(DPEPO)] (2), and [Tb(PPI)(3)(DPEPO)] (3) [where HPPI = 3-pheny1-4-propanoyl-5-isoxazolone and DPEPO = bis(2(diphenylphosphino)phenyl)ether oxide] have been s ...
