"Multifunctional molecule-based magnets : slow relaxation, luminescence and ferroelectricity."

Lundi 1er Avril 2019

Amphi Astier 

Abstract :

Coordination chemistry of lanthanide ions allows the tailored design of multifunctional molecule-based materials. We investigate here by using luminescent and magnetically anisotropic lanthanide ions assembled with enantiopure ligands the synthesis of high-temperature molecular ferroelectrics exhibiting Single-Molecule Magnet behavior and lanthanide luminescence. These systems exhibit an electrical bistability above 180 K of the Curie temperature of BaTiO3 while investigation of the magnetoelcetrical coupling at room temperature confirms their great potentiality.
