INSA Rennes is the largest public engineering school in Brittany. It welcomes 2,040 students and apprentices. Each year, over 340 engineers, 60 master's students, and 40 PhDs graduate from the school. With 9 academic departments—including 8 engineering specializations and 1 apprenticeship program—and overseeing 7 research laboratories, INSA employs around 540 public service staff (including teaching researchers, lecturers, and administrative and technical staff), along with over 70 part-time instructors from industry.

During this two-year postdoctoral research project funded by the ANR (French National Research Agency), the selected candidate will join the INSA component of the Solid State Chemistry and Materials team at the Institut des Sciences Chimiques de Rennes (more information available at: https://iscr-csm.insa-rennes.fr/members/). The candidate will become part of a multidisciplinary team of ca. 20 people, composed of researchers, faculty members, and doctoral/postdoctoral students. More specifically, The candidate will join a team consisting of a CNRS research director, an INSA lecturer, and a PhD student.

This postdoctoral research position is funded by the ANR PRC project "LumiCup," led by the INSA team in partnership with ICPEES (Institut de Chimie et Procédés pour l'Énergie, l'Environnement et la Santé), CNRS–University of Strasbourg. The candidate will be in regular collaboration with this partner. Synthetic work and structural and photophysical characterizations will be carried out within the INSA group, while theoretical studies will be pursued in close collaboration with researchers from the University of Rennes, including another postdoctoral researcher also hired for this ANR project.

A description of the available equipment for laboratory members is available at: https://iscr-csm.insa-rennes.fr/lab-facilities/. Additionally, the full range of instruments at the Institut des Sciences Chimiques de Rennes (https://iscr.univ-rennes.fr/facilities-equipment), including NMR spectrometers and single-crystal X-ray diffractometers, will also be accessible as needed for the development of this research.

The Project
Luminescent materials have become essential in numerous everyday applications such as lighting, displays, and detection systems. A current challenge is to develop multifunctional, stimulus-responsive materials addressing various needs, such as the detection of hazardous chemical substances (chemical weapons, poisons) or serving as luminescent markers for quality control, traceability, and anti-counterfeiting.

This research work will focus on the preparation of novel photoactive molecular systems based on Cu(I) precursors—a non-strategic and abundant metal. It aims to develop luminescent Cu(I)-based monomers and corresponding supramolecular luminescent polymers. The synthetic approach adopted in this project will be general and adaptable, paving the way for new families of efficient and environmentally friendly luminophores.

Based on straightforward and already-established synthetic methods developed in the lab, this project will generate a wide variety of structures and associated photophysical properties. This will enable the emergence of innovative materials combining intrinsic luminescence with sensitivity to external stimuli (temperature, pressure, atmosphere, solvents...), offering a broad range of emission colors and behaviors. The approach will notably include monomers with ESIPT properties developed at ICPEES, which will be used as linking ligands with Cu(I) TADF-emitting precursors to obtain supramolecular polymers with enhanced luminescence efficiency and innovative sensitivity to external stimuli.

The new derivatives will be characterized using various techniques such as powder and single-crystal X-ray diffraction, NMR, UV-Vis, and IR spectroscopy. Their photophysical properties will be studied in the solid state as a function of temperature (emission spectra, quantum yield measurements, and excited-state lifetimes), allowing to elucidate the electronic structure of the prepared compounds in both ground and excited states. The most efficient compounds will be embedded into various matrices, and device performances will be assessed with the aim of developing prototypes for real-world applications.

As part of this research, the recruited candidate may be invited to actively participate in ongoing collaborations within the group (including short-term research visits), with our partner at ICPEES, as well as with the research groups of Prof. Dr. Manfred Scheer at the University of Regensburg (Germany) and Prof. Leonard MacGillivray at the University of Sherbrooke (Canada).
