Description of the research group

The team is made up of (bio) physicists and physico-chemists experimenters whose research topics are:

  1. The electronic and magnetic properties of:
    a) molecules and molecular materials (molecular architectures);
    b) nanomaterials of various origin (polymers, thin coasts (layer), etc.);
  2. The objects of biological interest (proteins, membrane structures, etc.) with a particular interest in aspects of structural biology.
  3. The Quantum information.

Topics

  • Magnetic properties of nanomaterials
  • Molecular electronics
  • Biophysics: oxidative stress, structural biology
  • Spin Qubits

Research tools

¤ Electron Paramagnetic Resonance Spectroscopies
¤ Molecular Orbital Calculation Methods of  Functional Density Type (DFT)
¤ Systems of studies:

  • Conjugated systems
  • Coordination complexes
  • Nanoparticles
  • Molecules of biological interest and / or biomimetic.

List of equipment and devices

  • Bruker Elexys E580 in continuous and pulse mode: X-band (10 GHz), Electron nuclear double resonance (ENDOR) et double electron–electron resonance (DEER).
  • Bruker EMX Plus continuous mode, X-band (10 GHz), Q-band (35 GHz).
  • Bruker ECS106 continuous mode, X-band (10 GHz).
  • Bruker ESP300, continuous mode, X-band (10 GHz).
  • Accessories for electrochemistry in situ: potentiostat, cells adapted to EPR.
  • Accessories for the optical illumination in situ: EPR resonator and UV-visible Ar-Kr mixed gas laser.
  • Accessories for cryogenics temperatures between room temperature and 1.7 K and accessories authorizing high temperatures until 600 K.

Additionnal information

Node of the Research Infrastructure (IR 3443) EPR of the CNRS 'Renard',  registered in the 'Large Equipments / Large Research Infrastructures' of the CNRS: http://renard.univ-lille1.fr/. The laboratory answers via this platform to the requests for EPR analysis in fluid, or frozen solution, on support or on single-crystal.  Experiments are adapted and optimized for diverse recording support.

For further information, contact the person in charge of the platform Nolwenn Le Breton and visit the POMAM laboratory website: https://pomam.chimie.unistra.fr/
