Synthesis and spectroscopy of anionic tridentate benzimidazole-pyridine carboxylate and tetrazolate chromophore ligands

We report on seven new anionic benzimidazole-pyridine carboxylate and tetrazolate tridentate (NNO)-N-boolean AND-O-boolean AND and (NNN)-N-boolean AND-N-boolean AND ligands that are modified with chromophore (phenyl, biphenyl, naphthyl) and solubilizing gr ...

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

Jean-Claude Bünzli, Rosario Scopelliti, 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 ...

Tridentate Benzimidazole-Pyridine-Tetrazolates as Sensitizers of Europium Luminescence

Jean-Claude Bünzli, Rosario Scopelliti, 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 ...

The luminescence of NaxEu3+(2−x)/3MoO4 scheelites depends on the number of Eu-clusters occurring in their incommensurately modulated structure

Jean-Claude Bünzli, Gervais Chapuis, Alla Arakcheeva, Philip Pattison, Dmitry Logvinovich, Svetlana Eliseeva

Scheelite related compounds with general formula Mn(XO4)m are of interest owing to their optical properties, stability and relatively simple preparation. Eu3+-containing scheelites are considered as red emitting phosphors and the main factors affecting the ...

Synthesis and Photophysical Properties of Ln(III)-DOTA-Bipy Complexes and Ln(III)-DOTA-Bipy-Ru-II Coordination Conjugates

Jean-Claude Bünzli, Svetlana Eliseeva

The synthesis and the systematic and comparative photo-physical study of a series of visible (Eu-III, Tb-III) and NIR-emitting (Nd-III, Yb-III) lanthanide complexes (Ln(2)L) and ruthenium lanthanide coordination conjugates (Ln(2)LRu) are reported. The Gd-I ...

N-Aryl Chromophore Ligands for Bright Europium Luminescence

Jean-Claude Bünzli, Rosario Scopelliti, Svetlana Eliseeva

Sterically hindered N-aryl-benzimidazole pyridine-2-carboxylic acids (aryl = phenyl, 4-biphenyl, 2-naphthyl) readily form homoleptic, neutral, nine-coordinate europium complexes which display efficient sensitized luminescence in solid state and in dichloro ...
