EMMD - Electrochemistry, Molecular Materials and Devices

EMMD (Electrochemistry, Molecular Materials and Devices) research activities are devoted to molecular materials, from molecules to materials and from materials to devices. Electrochemical techniques are used to synthesize, to immobilize and to detect chemical or biological species. The synthetic aspect relates to the synthesis and functionalization of macrocycles (porphyrins, phthalocyanines…) and polymers. The analytical aspect 1) exploits the redox properties of compounds or sensitive layers (biomaterials, conducting polymers, charge-transfer complexes, …) for the characterization and the detection of biomolecules or chemical pollutants in sensor devices; 2) to apprehend reaction mechanism of molecular processes. Our projects are focused on applications in the fields of environment, health and food industry.

I am interested in the chemistry of transition metals and main group elements (included, but not limited to, titanium and phosphorus). Particular emphasis is placed on:

  • ü The synthesis and characterisation of organometallic compounds.
  • ü  The elucidation of questions pertaining to the nature of metal-ligand interactions: links between experiments and theory, epistemological implications (what is a chemical bond?).
  • ü  Reactivity studies, notably in small molecule activation (H2, CO2, P4).
  • ü  Applications to catalysis.

Current projects:

With P. Le Gendre (ICMUB) and G. Erker (WWU Münster), we are studying the properties of Cp2Ti+ or Cp2Zr+ cations stabilised by a phosphido (PR2-) or amido (NR2-) ligand. These complexes contain a Lewis acid and a Lewis base inside the same molecule, which enables them to activate organic substrates (H2, CO2…)in a cooperative manner (acid-base cooperativity).

This work has shown that Ti-P bonds could be cleaved homolytically to generate a Ti(III) metalloradical and a phosphinyl radical (PR2). We now wish to harness this reactivity and prepare diradical catalysts which could act cooperatively (radical cooperativity). To this end, we are developing new ligand frameworks in order to stabilise these reactive species.

Other ongoing projects include:

  • With P. Le Gendre (ICMUB), S. Dagorne (Unistra) and A. Auffrant (École polytechnique), the catalytic applications of “phosphasalen” complexes.
  • With M. Iglesias Alonso (Universidad de Zaragoza), the coordination chemistry of “N-heterocyclic olefin” complexes of Ti and Zr.
