Acridone-Benzimidazole Ring-Fused Ligands: A New Class of Sensitizers of Lanthanide Luminescence via Low-Energy Excitation

Frédéric Gumy

Two monotopic tridentate ligands, namely HLAB1 and HLAB2 have been synthesized which feature an acridone chromophore fused on a benzimidazolepyridine framework. They differ from each other by their connection points between a N-methylacridone and a N-methy ...

Lanthanide luminescence efficiency in eight- and nine-coordinate complexes: Role of the radiative lifetime

Anne-Sophie Chauvin, Svetlana Eliseeva

The photophysical parameters for the sensitization of metal-centred luminescence are analyzed in two series of complexes with tridentate and hexadentate ligands having NxOy chelating units. In particular, the radiative lifetime tau(rad) is experimentally e ...

Modulating the Near-Infrared Luminescence of Neodymium and Ytterbium Complexes with Tridentate Ligands Based on Benzoxazole-Substituted 8-Hydroxyquinolines

Rosario Scopelliti, Jean-Claude Bünzli, Frédéric Gumy

An improved synthesis of 2-(2′-benzothiazole)- and 2-(2′-benzoxazole)-8-hydroxyquinoline ligands that combine a tridentate N,N,O-chelating unit for metal binding and extended chromophore for light harvesting is developed. The 2-(2′-benzoxazole)-8-hydroxyqu ...

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 ...
