Job description
Offer DescriptionCall for expression of interest descriptionThe is a highly prestigious renowned EU-funded scheme. It offers talented scientists a unique chance to set up 2-year research and training projects with the support of a supervising team. Besides providing an attractive grant, it represents a major opportunity to boost the career of promising researchers.The ISCR-OMC is thus looking for excellent postdoctoral researchers with an international profile to write a persuasive proposal to apply for a Marie S. Curie Postdoctoral Fellowship grant in 2024 (deadline of the EU call set on 11 September 2024). The topic and research team presented below have been identified in this regard.Main Research Field
- Chemistry (CHE)
Research sub-field(s)Chiral organic molecular materials with closed-and open-shell electronic configuration for optoelectronic applicationsKeywordsOrganic molecular materials, chirality, circularly polarized luminescence, optoelectronicsResearch project descriptionDesigning organic materials that combine several functionalities (luminescence, conductivity, magnetism) is of strong interest for increasing the performances of modern electronic devices (OLED, photovoltaics, transistors).In this domain, chiral p-conjugated molecules have recently appeared as a new direction, due to their specific interaction with circularly polarized (CP) light, and their unique electron spin filtering ability, known as Chiral Induced Spin Selectivity (CISS) effect. 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.The objective of the project aims is to design unprecedented organic chiral compounds with both closed- and open-shell structures, and investigate their resulting innovative properties in practical devices, arising from the molecular union of chirality and magnetism. The resulting molecular materials will be of high potential for display applications, by developing CP-organic light emitting devices (OLEDs) with 100% of theoretical efficiency, and in innovative CP-light-responsive spin-filtering devices for information processing and storage.This multidisciplinary research project will be conducted as a spin-off of the European Research Council project (Grant Agreement number: 101041516-SHIFUMI-ERC starting grant (StG), )and will be an excellent opportunity for the Postdoc candidate to acquire scientific and soft skills valuable for academic and professional careers.Supervisor(s)The Postdoctoral Fellow will be supervised by Dr. Ludovic Favereau (LF, )After previous research experiences in Nantes (PhD 2014) and in Oxford (Postdoc 2015), LF was then recruited as a Research Fellow at the CNRS in October 2015 at the Rennes Institute of Chemical Sciences ( ), where he joined the Organometallics: Materials & Catalysis (OMC) team to work with Dr. Jeanne Crassous. Since then, he develops his research line devoted to organic chiral p-conjugated molecular systems for chiral optoelectronic applications. His research interests notably include the design of chiral organic closed- and open-shell p-conjugated molecules with intense chiroptical properties (circular dichroism, circularly polarized luminescence) to explore the potential of chirality in material science (OLED, OPV, …).LF was awarded two times the “CNRS Excellence Prime” in 2016 and 2022, and the “Marc Julia Award” from the French Organic Chemistry Division in 2019.He recently obtained an ERC StG (2022) named SHIFUMI, which aims to design chiral organic radicals, and to study their novel properties of luminescence and electronic conduction. These objectives are notably 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.Selected publications:Organic radicals with inversion of SOMO and HOMO energies and potential applications in optoelectronicsS.

Favereau*, .Department/ResearchIt is envisaged that the most part of the project will be carried out within the laboratory of LF, the (ISCR), or using facilities of the University of Rennes (UNIVREN) to which the ISCR belongs.UNIVREN has for many years been considered the top university in France and is amongst the 5% international HEIs listed in the international rankings ( ). ISCR provides LF the necessary research space to develop his research activities. Apart from all synthetic chemistry bench space (equipped fume hoods), the group has at its disposal (spectro)electrochemistry and UV-vis absorption spectroscopy, HPLC and GCMS instrumentation, a gradient sublimation system and notably its own chiral and optoelectronic platforms including specifically the state-of-the-art chiroptical spectrometers (electronic circular dichroism, circularly polarized luminescence). The chemistry department ensures also access to state-of-the-art including facilities related to routine compound characterization facilities (NMR, MS and XRD facilities) as well as specialized facilities including AFM, TEM, SEM, TGA, SMC, diffuse reflectance instrumentation, microwave reactors. Further, cutting-edge facilities are available within the department including advanced spectroscopic equipment (e.g., emission, ultra-fast luminescence spectroscopy) and light-emitting device fabrication and testing facilities. The infrastructure coupled with the personal supervision and stimulating scientific atmosphere provided by LF and more widely by the ISCR maximizes the chances for a successful outcome for the proposed research.LocationCampus Beaulieu, University of Rennes 1, RennesSuggestion for interdisciplinary / intersectoral secondments and placementsLF has developed a solid network of international collaborations in several areas of research. Potential secondments are possible to learn and develop additional skills in advanced photophysical and magnetic characterizations for instance (collab. E.
