Lanthanide Luminescent Bioprobes (LLBs)

Lanthanide luminescent bioprobes (LLBs) are amongst the most sensitive luminescent probes because their excited states are long-lived, which allows time-resolved detection (TRD) of their luminescence, boosting the signal-to-noise ratio and the sensitivity; ...

Structural, Spectroscopic, and Thermodynamic Consequences of Anti-Chelate Effect in Nine-Coordinate Lanthanide Podates

Jean-Claude Bünzli, Frédéric Gumy

The connection of three tridentate 2,6-bis(1-ethyl-benzimidazol-2-yl)pyridine binding units to an extended sulfurcontaining tripodal anchor in the ligand L9 yields nine-coordinate podates [Ln(L9)]3+ upon reaction with trivalent lanthanides, Ln(III). Struct ...

Highly Luminescent Homoleptic Europium Chelates

Rosario Scopelliti, Jean-Claude Bünzli, Frédéric Gumy

The need for efficient and photostable lanthanide luminescent materials is dramatically increasing, in particular with respect to their growing application in lighting devices and biosciences. To this end, we have developed a facile synthesis of benzimidaz ...

Benzothiazole- and Benzoxazole-Substituted Pyridine-2-Carboxylates as Efficient Sensitizers of Europium Luminescence

Rosario Scopelliti, Jean-Claude Bünzli, Frédéric Gumy

A facile synthesis of benzothiazole- and benzoxazole-substituted pyridine-2-carboxylic acids has been developed. These ligands form mononuclear nine-coordinate complexes [Ln(κ3-ligand)2(κ1-ligand)(H2O)2] with light and heavy trivalent lanthanides, as estab ...

Time-resolved lanthanide luminescence for lab-on-a-chip detection of biomarkers on cancerous tissues

Martinus Gijs, Jean-Claude Bünzli, Caroline Vandevyver, Venkataragavalu Sivagnanam, Bo Song, Hans-Anton Lehr

PDMS-based microfluidic devices combined with lanthanide-based immunocomplexes have been successfully tested for the multiplex detection of biomarkers on cancerous tissues, revealing an enhanced sensitivity compared to classical organic dyes. ...

Homo- and Heterodinuclear Helicates of Lanthanide(III), Zinc(II) and Aluminium(III) Based on 8-Hydroxyquinoline Ligands

Jean-Claude Bünzli, Frédéric Gumy

Homonuclear helicates with rare-earth-metal(III) ions or heteronuclear derivatives with rare-earth-metal and aluminium or zinc centres are obtained in alkali-metal-templated selfassembly processes from isobutenylidene- bridged homoditopic bis(2-carb-Gamido ...

Tuning the self-assembly of lanthanide triple stranded heterobimetallic helicates by ligand design

Rosario Scopelliti, Jean-Claude Bünzli, Thomas Binderup Jensen

The heterobitopic ligands LAB4 and LAB5 have been designed and synthesised with the ultimate aim of self-assembling dual-function lanthanide complexes containing either a magnetic and a luminescent probe or two luminescent probes emitting at different wave ...

Structural and Luminescent Properties of Micro- and Nanosized Particles of Lanthanide Terephthalate Coordination Polymers

Jean-Claude Bünzli, Frédéric Gumy

Reaction in water between rare earth ions (Ln ) Y, La-Tm, except Pm) and the sodium salt of terephthalic acid leads to a family of lanthanide-based coordination polymers of general formula [Ln2(C8H4O4)3(H2O)4]n with Ln ) La-Tm or Y. The isostructurality of ...

Near-Infrared Luminescence of Nine-Coordinate Neodymium Complexes with Benzimidazole-Substituted 8-Hydroxyquinolines

Rosario Scopelliti, Jean-Claude Bünzli, Frédéric Gumy

A new class of benzimidazole-substituted 8-hydroxyquinoline ligands has been prepared that contain a monoanionic tridentate N,N,O-coordinating unit. These ligands form charge-neutral lanthanide complexes of the type [Ln(LR) 3] · nH2O or [Ln2(L2)3] · nH2O ( ...
