Education and professional experience

Holder of a chemical engineering degree from the National Institute of Applied Sciences of Rouen and a Master 2 from the University of Rouen, Ludovic Favereau, then, carried out his PhD at the University of Nantes, in the CEISAM laboratory (Chemistry and Interdisciplinarity: Synthesis, Analysis and Modeling), within the team of Doctor F. Odobel. His work included the synthesis of molecular architectures mimicking the Z-scheme of the natural photosynthesis and the improvement of hybrid dye sensitized solar cells. After that, in 2014, he obtained a postdoctoral fellowship to work at the University of Oxford (England) under the supervision of Prof. H. Anderson, on the synthesis of multidimensional π-conjugated porphyrin molecular systems directed by template synthesis.

He was then recruited as a Research Fellow at the CNRS in October 2015 at the Rennes Institute of Chemical Sciences (ISCR), where he joined the Organometallics: Materials & Catalysis (OMC) team to work with Dr. Jeanne Crassous. His research interests notably include the design of chiral organic closed- and open-shell π-conjugated molecules with intense chiroptical properties (circular dichroism, circularly polarized luminescence) to explore the potential of chirality in material science (OLED, OPV, ...).

ERC Project : SHIFUMI

Project designation: SHIFUMI - SOMO-HOMO Inversion For chiral open-shell  π-conjUgated systeMs

Designing organic materials combining several functionalities (luminescence, conductivity, magnetism) is of great interest for increasing the performance of opto-electronic devices used in displays (OLED), photovoltaics or even electronic conduction (transistors). In this field, the introduction of the property of chirality to π-conjugated systems has recently appeared as a new direction of research, resulting in new properties such as a specific interaction of the chiral material with so-called circularly polarized light or even a spin-polarized electron conduction (chirality induced spin selectivity, CISS). While extensive research is conducted on chiral closed-shell systems, few attentions have been devoted to their open-shell analogs, despite the added-value of spin property, attracting significant attention in a range of scientific domains such as display technologies, cryptography and spintronics.

The SHIFUMI project aims to design this type of organic material, more commonly called chiral radicals, and to study their novel properties of luminescence and electronic conduction. This objective will be achieved via a new conceptual approach, involving a control of electronic orbitals linked to fundamental aspects of chemical and configurational stability of chiral radicals.

This project will provide new insights on this specific class of organic materials which have not yet been explored, despite their strong potential for increasing the efficiency of display devices or even information processing and storage, suggesting new perspectives in "chiral" organic electronics.
