Organisation/Company CNRS Department Laboratoire de Chimie Moléculaire Research Field Chemistry Physics Researcher Profile First Stage Researcher (R1) Country France Application Deadline 17 Dec 2025 - 23:59 (UTC) Type of Contract Temporary Job Status Full-time Hours Per Week 35 Offer Starting Date 1 Feb 2026 Is the job funded through the EU Research Framework Programme? Not funded by a EU programme Is the Job related to staff position within a Research Infrastructure? NoOffer DescriptionThe mission will be to synthesize oxophilic metal complexes, particularly lanthanide complexes, supported by ligands of varied denticity (bidentate, tripodal, cyclopentadienyl-type ligands). The reactivity of these complexes will be studied towards CO2 with the objective to get highly reactive and selective systems. Different routes will be explored for the regeneration of the systems, either in the laboratory (electrochemistry, photochemistry) or in collaboration (cold plasmas) in order to achieve CO2 release under low energetic demands.ResponsibilitiesDevelop the organic synthesis of the targeted ligands of varied denticitySynthesize lanthanide complexes under inert atmosphereStudy the reactivity of the complexes towards small molecules, especially CO2Characterize the complexes using routine X-ray diffraction, NMR, UV-Vis and infrared spectroscopyDevelop electrochemical and photochemical methods for the regeneration of the systemsMonitor scientific developments related to the research topicPrepare written reports and communicate results according to the recommendations proposed by the funderParticipate in research seminarsWrite up research results in scientific publicationsSupervise PhD, master's and bachelor's students in the research groupEnsure the proper maintenance and operation of the synthesis roomsParticipate in the maintenance of the laboratory equipmentThe thematic group “f orbitals and reactivity” (https://lcm.ip-paris.fr/en/research/f-orbitals-and-reactivity ) of the Laboratory of Molecular Chemistry (UMR 9168) focuses on the synthesis and study of f-element and oxophilic metal complexes. A major research axis concerns the activation and transformation of small molecules, especially CO2. In the context of the energetic transition, the development of new techniques that allow capture, use and valorization of CO2 are major objectives. The two main challenges associated with direct air capture (DAC) are the relatively low concentration of CO2 in the atmosphere (425 ppm) and its high stability, which impose the design of highly selective systems that can be regenerated under low energetic demands.The postdoc fellow will work in the LCM (UMR 9168) at Ecole Polytechnique, a unit with a staff of around 35 people. The research themes developed in this laboratory are at the molecule-metal interface and concern the reactivity of coordination complexes and their use in catalysis. All aspects, from the most fundamental to the most applied, are involved. The laboratory benefits from the advantages of the Ecole Polytechnique campus, in the heart of the Saclay plateau, renowned for its scientific excellence. The laboratory has recognized expertise and state-of-the-art equipment in the field of organometallic chemistry and the synthesis of highly reactive compounds.We are looking for highly motivated candidates with a PhD in molecular inorganic chemistry. The candidate must be well-trained in organometallic synthesis and handling compounds under inert atmosphere. Very good knowledge in standard inorganic spectroscopy (X-ray, NMR, UV-Vis, IR) is essential for the project. The candidate will also be expected to take part in the work and life of the group.
