Research activities

We use the coordination chemistry of the rare-earth ions to produce advanced magnetic materials for data storage and quantum computation. This research address the Goal N°9 of UN Sustainable Develoment Goals (SDG): Build resilient infrastructure, promote sustainable industrialization and foster innovation.

Keywords : Lanthanides Coordination Chemistry, Molecular Magnetism, Luminescence, Single-Molecule Magnets (SMMs), Single-Chain Magnets (SCMs), Radical Ligands, Metal-Organic Frameworks, Multifunctional Materials, Surfaces.

 
  • Research Topic 1: Lanthanide-based Single-Molecule Magnets

We are developing lanthanide-based molecules with strong luminescence or interesting magnetic behavior.  In this last case we are targeting Single-Molecule Magnet (SMM) properties, i.e. molecules that are able to behave as magnets at the nanometric scale. We are also particularly interested in Single-Chain Magnets (SCM) that are mono-dimensional extension of SMM and are expected to present more robust magnetic slow relaxation.

  • Research Topic 2: SMM and Surfaces

We are focusing our efforts on the investigation of films of luminescent SMM for the creation of luminescent or magnetic devices. For example, in a collaboration with the Ningbo Institute of Science (China) we have built a electroluminescent device in which the luminescence in controlled by the electro-migration of copper ions

We also strongly collaborate with the University of Florence (La.M.M.) to deposit films of SMM on surfaces. As an illustration, we have shown that thin films of SMM can be obtained by sublimation of fluorinated molecules. By using Muons Spin Spectroscopy (µSR, collab. PSI) we show that the individual SMM behavior is preserved in the deposition process and is still present in these thin films.
