Description du sujet de thèse

Although chirality is recognized as a key factor in many areas of chemistry and biology, its role in photoinduced electron transfer (PeT) processes remains to be fully elucidated. While these phenomena have been described for various mono- or multi-component systems, very few reports have been made regarding chirality, and even fewer addressing the impact of polarized light on PeT. Understanding the role of chirality would pave the way for potential applications, including the development of artificial photosynthesis, the chiral recognition of relevant biomolecules, or the stereoselective control of the biological activity of chiral molecules such as proteins. The primary objective of the thesis will be the synthesis and characterization of new large-scale chiral architectures (foldamers) to understand how chirality influences light-induced electron transfer at different time and length scales. The thesis is funded by the ANR (ChiraPET / https://anr.fr/Projet-ANR-24-CE07-1874). The PhD student's work will be carried out in collaboration with Dr. Céline Olivier and Dr. Nathan McClenaghan (ISM- Bordeaux). Activities include:

Multi-step organic synthesis
Solid-phase synthesis
Analysis and purification by HPLC and GPC
Crystallogenesis
NMR structure resolution
