Small Molecule Activation: Atom Economy and Sustainable Processes
We aim at reacting our novel complexes with small molecules, such as nitrogen, carbon dioxide, nitrogen protoxyde, white phosphorus and carbon monoxide in order to lean toward their transformation in more valuable products.

Building new Optical Active Materials for Selective P-S and P-O Hydrolysis
We consider the use of divalent lanthanides complexes as starting materials to build large trivalent soluble assemblies that may be used as catalysts for selective P-S or P-O hydrolysis. These new clusters may also be used as precursors for the formation of nanomaterial containing lanthanides for a variety of applications.
Spectroscopy and Theory: Lanthanides and Transitions metals
The investigation of the unusual electronic structure of coordination compounds and organometallics is a topic of great interest for us. We use X-ray studies, magnetism, EPR, NMR, optical spectroscopy and theoretical analyses. In this area, we have many collaborations with french and international research groups.
LanAsCat: Heterobimetallic Complexes for C-H activation
This is a recent ERC granted project that aims at developing a new type of organometallics containing lanthanides, redox non-innocent ligands and transitions metals is herein proposed: the first providing reversible electron(s) source(s) (remote control), the second acting as electron(s) reservoir and controlling the electron correlation strength (“dimmer switch”), and the last being the site of the selective catalytic reaction. The principal goal is to synthesize active compounds with respect to C-H bonds activation and methane activation is regarded as an ultimate achievement. It will be our main research focus for the next five years.
ReDivaLan: Electron Transfer Reactivity of Organolanthanides
This project was an ANR (Agence National de la Recherche) funded projet that ended in 2018 that aimed at drawing a relation between the odd electronic structure of organolanthanides and their unusual reactivity: it was a collaborative grant together with O. Maury (ENS Lyon), C. Clavaguéra (Orsay University) and L. Maron (INSA Toulouse). We are now expending the concept for the design of Single Molecules Magnets
Synthesis of Original Metal Complexes with Redox Non-Innocent Ligands
We design soluble (Figure) and original organometallic complexes of low-valent transitions metals and of divalent lanthanides. These soluble complexes may be used as precursors for further reactivity or for the synthesis more elaborated molecules containing redox non-innocent ligands.
