Welcome to the M3 website !

The Molecular Materials & Magnetism (M3) team is a research group lead by Rodolphe Clérac since 2001, and composed of Harald Bock, Fabien Durola, Pierre Dechambenoit, Corine Mathonière, Xavier Brilland and  Mathieu Rouzières.
The M3 research group is working at the Centre de Recherche Paul Pascal (CRPP), a CNRS scientific center situated on the campus of the Université de Bordeaux.


M3 research ACTIVITIES

Team M3 a research group for molecular materials and magnetism

The Molecular Materials & Magnetism (M3) team is working on new molecules and molecule-based materials.

From their synthesis to their characterization, in order to promote and control interesting physical properties such as magnetism, electrical conductivity, superconductivity, porosity, spin-crossover, single-molecule and single-chain magnets, magnets…

Five main themes of research are currently being developed.

  • Macroconjugated polyaromatic molecules
  • Molecule-based magnets and conducting magnets (with high critical temperature)
  • Single-molecule and single-chain magnets (and their derivatives) with high blocking temperatures or photo-switching properties
  • Spin-crossover and paramagnetic metal-metal bonded complexes
  • Magnetic and/or electro-active solutions and liquid-crystals.

In all these projects, our approach is comprehensive, from synthesis to detailed studies of the physical properties and their theoretical description. These different projects benefit from many national and international collaborations and also our involvement in different national and European networks.
