Abstract Single-ion anisotropy is vital for the observation of Single-Molecule Magnet (SMM) properties (i.e., a slow dynamics of the magnetization) in lanthanide-based systems. In the case of europium, the occurrence of this phenomenon has been inhib

The effect of ligands' energy levels on thermal dependence of lanthanide emission was examined to create new molecular nanothermometers. A series of Ln2Ga8L8′L8″metallacrowns (shorthand Ln2L8′), where Ln = Gd3+, Tb3+, or Sm3+(H3L′ = salicylhy

Publikováno v: Inorganic Chemistry Frontiers. 8:2611-2623

Two GdIII FeIII4 metallacrown complexes are presented and analyzed for their magnetic properties. One of these species is newly identified and exhibits a bent ring geometry as opposed to the more conventional flatter conformation of the other. Both c

International audience; Single lanthanide(III) ion white light emission is in high demand since it provides the advantage of requiring only one chromophore for the control of the color. Herein, a series of Ga3+/Dy3+ metallacrowns (MCs) is presented,
