Offer Description

Organic-inorganic hybrid materials based on copper(I) complexes display particularly interesting optical properties due to their stimuli-responsive character. These luminescence properties are characterized by a change in emission under the effect of external stimuli, such as pressure (mechanochromism), temperature (thermochromism) or exposure to solvent vapors (vapochromism). Applications for these materials include detection, lighting and anti-counterfeiting. These copper-based materials have attracted growing interest in recent years, both from an economic and environmental point of view, due to the low cost of copper element and its low toxicity. Recent studies have shown the potential of these materials as an alternative to hybrid perovskites, which present toxicity problems due to lead. For the development of this fast-growing family of copper materials, in-depth knowledge of their optical properties is essential, and in particular for their further optimization. Indeed, the emissive excited states of these materials, often multiple and different in nature, are still difficult to determine precisely. In this context, the aim of this thesis project is to rationalize the optical properties of these materials through an approach combining experiment and theory.

The thesis project will focus on the synthesis, characterization and rationalization of the luminescence properties of new copper(I)-based materials. The establishment of structure/property relationships will be at the heart of the research. In particular, X-ray diffraction/total scattering techniques as well as transient Raman and FTIR spectroscopies will be employed. In parallel, DFT calculations will be carried out to simulate emission and vibrational spectra, in order to interpret experimental results. Solid-state molecular structures will be studied, and the impact of intermolecular interactions (extended solid) on luminescence properties will also be evaluated by DFT. This thesis project should enable us to gain in-depth knowledge of the optical properties of these materials with significant applicative potential.

Required Skills

• Skills in characterizing materials with optical properties.
• Knowledge of theoretical chemistry.
• Good writing skills (reports and presentations).
• Motivation, rigor, autonomy, teamwork.
• Good level of written and spoken English.
