Missions

The development of circularly polarized light (CPL) sources exhibiting strong dissymmetry (ratio of right- to left-circularly polarized emission) has been a highly active area of research in recent years. While current devices do not achieve emission dissymmetry values above 50%, we are exploring a novel strategy aimed at producing integrated laser sources by incorporating CPL emitters within chiral polymer matrices.
The recruited researcher will be responsible for the preparation and characterization of lanthanide(III) complexes that serve as CPL emitters. A significant part of the work will involve the synthesis and purification of organic ligands to be coordinated to various lanthanide ions. The optical and chiroptical properties of these compounds, in the visible and near-infrared ranges, will also be characterized prior to their transfer to project partners.

Activities

• Synthesis, purification, and characterization of ligands and coordination complexes
• Crystallization and incorporation into polymer matrices
• Spectroscopic studies in solution and in the solid state (absorption, emission, circularly polarized luminescence)
• Preparation of scientific reports

Skills

• Education: Master's degree (MSc) or PhD in chemistry
• Expertise in organic synthesis and purification (chromatography)
• Experience with inert-atmosphere techniques (Schlenk methods)
• Routine molecular characterization (NMR, IR, MS)
• Experience with optical spectroscopy (UV–vis, fluorescence, etc.) would be an asset
• Additional skills:
– Strong organizational abilities, rigor, and interest in interdisciplinary research
– Ability to present and discuss results in English within an international team

Work Context

This position is funded by the ANR project iCPLaser, in collaboration with two Lyon-based institutes: the Laboratoire de Chimie at ENS de Lyon (Laure Guy) and the Institut Lumière Matière (Stéphan Guy). These partners will carry out material processing and device fabrication. Close collaboration between the chemistry teams will ensure compatibility between the luminescent complexes and the polymer matrices. The research engineer will participate in regular project meetings.
The work will be conducted under the supervision of Dr. François Riobé (CNRS Research Scientist) within the Molecules and Switchable Materials group, which brings together synthetic chemists investigating the properties of metal complexes, particularly in the solid state (e.g., spin transition, chirality-related properties, charge transport).


Created in 1995, the Institute of Chemistry of Condensed Matter of Bordeaux (ICMCB) focuses its research on Solid-State Chemistry, Materials Science, and Chemical Processes — designing, synthesizing, shaping, and characterizing materials to discover, control, and optimize specific functions. The ICMCB conducts fundamental research on model materials and/or materials with potential applications.

The ICMCB is a Joint Research Unit (UMR) with an average of 280 staff members (both permanent and non-permanent) and three supervising institutions. It is hosted by the CNRS and classified as a full ZRR (Zone à Régime Restrictif).

The position is located in a sector subject to the protection of scientific and technical potential (PPST). Consequently, in accordance with current regulations, the appointment of the selected candidate must be authorized by the competent authority of the French Ministry of Higher Education and Research (MESR).

The position is located in a sector under the protection of scientific and technical potential (PPST), and therefore requires, in accordance with the regulations, that your arrival is authorized by the competent authority of the MESR.

Constraints and risks
