Research in the ERMMES team is at the crossroad of molecular chemistry and materials sciences. The team concieves materials bearing original physical properties and builds correlations between structures and properties. Initialy, the team focused only on molecular magnetism, which is the design of magnetic materials thanks to molecular chemistry methods. Our team is therefore expert in both the synthesis and the characterisation and rationalisation of magnetic properties. These research axis rely on the low-temperature physical measurements platform (MPBT) at UPMC.
Our expertise leads us to design and study in the last few years :

  • switchable molecules for which optical or magnetic properties are modified by an external stimulus,
  • slow magnetic relaxation in single molecule magnets or single chain magnets being able to store magnetic information
  • multifunctional magnetic materials such as porous magnets answering specifically to host molecules.

This type of research being moved by curiosity, it lies on a very fundamental approach. Nevertheless, aware that our molecular systems bear a strong integration potential into molecule-based nanotechnologies, the fundamental study of the objects synthesized in our lab is now enriched by other research themes dealing with original molecular assemblies and hybrid systems such as :

  • inorganic nanoparticles decorated by complexes for information storage, medical imaging and hyperthermia,
  • hybrid ionic and electronic conductor molecular materials for cathode applications,
  • hybrid quantum dots for spintronics

The ERMMES team synthesizes multi-scale original materials (molecules, 1D materials, 2D and 3D networks, nanoparticles) based on mono- and poly-metallic molecular briks. This approach is based on the idea of molecular programming allowing to inject in the molecular precursor the chemical, structural and electronic information needed for the design of molecular architectures bearing the desired properties.

In support and in parallel of all these themes, our group develops research in X-ray absorption spectroscopies (XAS and XMCD) allowing the study of chemical and electronic local structures and of the magnetic properties of materials that do not bear long-distance order. On the other hand, paramagnetic NMR is also developped as a local probe to understand interaction mechanisms between magnetic centres.
