Molecular magnetism and spins dynamic

A significant part of the research activities within the IMNO team concern investigations on magnetism, involving either electronic (with studies on lanthanide-based multifunctional molecular materials), and nuclear spins (with fundamental developments on solid state NMR spectroscopy). Among the recent investigations, we can cite the development of novel strategies for the isotopic labeling of oxygen-17, in view of elucidating the structure and reactivity of complex systems using high resolution 17O solid-state NMR, and the development of molecular materials with magnetic, luminescent, ferroelectric and chiral properties.

Selection of recent research topics developed

  • New strategies for the isotopic enrichment in oxygen-17 have been developed, in view of analyzing the structure and reactivity of surfaces and interfaces using high-resolution 17O NMR. This new research activity relies on a novel oxygen-17 labeling approach involving mechanochemistry, which enables to produce a wide variety of organic and inorganic precursors of synthetic interest, in a fast and affordable way. Thanks to this new labeling approach, new developments in high-resolution 17O NMR are being performed, and the elucidation of the structure and reactivity of complex systems is being looked into, through the characterization of the oxygen bonding environments at the surface of nanomaterials or at the interface of different phases.

  • Lanthanide-based complexes and molecular materials involving cyanide ligands : This research activity aims at preparing complexes and molecular (nano)materials which present simultaneously several physical properties (e.g. magnetic and optical properties). The study of the correlation and/or synergy between the different properties is at the heart of this research.

  • Analysis of complex magnetic systems such as core-shell particles, which allows to study a hybrid system with synergistic effects between the core and shell in an addressable manner. This approach opens up many perspectives in the study of the dependence of the memory effect, fast spins switchable nano-domains and their propagation, etc. This research includes a part of experimental development and a unique approach to study magnetic nano-objects synthesized in the team. It is the first step towards the integration of molecular (nano)materials in devices, and positions the team in the field of nanotechnology.
