Abstract: Inert and optically active pseudo-octahedral CrIIIN6 and RuIIN6 chromophores have been incorporated by self-assembly into heterobimetallic triple-stranded helicates HHH-[CrLnL3]6+ and HHH-[RuLnL3]5+. The crystal structures of CrLnL36 (L ...
There are only few structural thermodynamic and kinetic studies on labile octahedral complexes available today. Octahedral paramagnetic compounds of cobalt(II) have an optimum electronic relaxation leading to NMR spectra with good resolution. Therefore, th ...
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 ( ...
The segmental bidentate–tridentate–bidentate ligand L2 reacts with MII (M = Cr, Zn) and LnIII (Ln = La, Eu, Gd, Tb, Lu) to give the heterotrimetallic triple-stranded helicates [MLnM(L2)3]7+. For M = ZnII, the isolated complexes ZnLnZn(L2)37 (Ln = ...
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 ...
Classical molecular dynamics simulations with a force field adapted to the family of Gd3+ polyaminocarboxylate complexes have been successfully applied on two macrocyclic ([Gd(DOTA)(H2O)]- and [Gd(DO3A)(H2O)2]) and two acyclic ([Gd(DTPA)(H2O)]2- and [Gd(EG ...
Since contrasts agents are used in magnetic resonance imaging (MRI), numerous efforts have been done to increase their relaxivity (parameter allowing to quantify contrast agent efficiency). Few years ago, the Merbach group developed the chelating agent DTT ...
