This internship project aims the preparation and study of the properties of molecular compounds known as single-molecule magnets. We will focus on chiral rare-earth ion (LnIII) complexes that are luminescent and behave like magnets. The idea behind this project is to probe the synergy between optical and magnetic properties, i.e. a magneto-optical effect, in molecular nano-magnets. The development of this project combines chemical synthesis, characterizations, and physical properties investigations. In a first step the syntheses of the ligand (organic chemistry) and of the metal complexes using different LnIII salts (coordination chemistry) will be performed. In each step of the process various characterizations such as NMR, IR, UV-vis, Circular Dichroism, and by X-ray diffraction techniques, will be performed to ensure the purities of the products. The crystal structures of the novel complexes will also be investigated. Then, the luminescence and magnetic properties will be investigated. This study will be completed by theoretical calculations performed (in collaboration with LCPQ from Toulouse University).
