Copper iodide-based materials exhibiting luminescent mechanochromic properties for the development of shock/strain sensors
Abstract: Materials whose luminescent properties can be modulated in response to external stimuli are attracting growing interest for the development of numerous applications, such as strain detection, optical recording, and information storage. Among these materials, mechanochromic luminescent materials are characterized by a change in their luminescence properties in response to external mechanical stress, such as grinding. Transition-metal-based materials—and in particular those based on copper(I) halide—are of interest due to their great structural diversity, their varied photophysical properties, and their economic and environmental advantages stemming from the low cost and limited toxicity of copper.
In this context, this thesis focuses on the study of new copper(I) iodide-based mechanochromic luminescent materials. New materials were synthesized, and their structure and optical properties were characterized. Particular attention was paid to understanding the relationships between the structure and optical properties of these compounds. The materials were also incorporated into polymer matrices, for example, to explore potential applications.

Copper iodide-based materials with luminescent mechanochromic properties for the development of shock/stress sensors
Abstract: Luminescent stimulus-responsive materials are receiving increasing attention due to their switchable optical properties in response to external stimuli, which lead to a variety of potential applications such as stress detection, optical recording, and information storage. Among these materials, luminescent mechanochromic materials are characterized by a change in their luminescence properties in response to external mechanical forces, such as grinding. Materials based on transition metals—particularly those based on copper(I) halide—are of interest due to their wide structural diversity, their broad range of photophysical properties, and their economic and environmental advantages stemming from the low cost and limited toxicity of copper.
In this context, this thesis focuses on the study of new luminescent mechanochromic materials based on copper(I) iodide. New materials have been synthesized, and their structure and optical properties have been characterized. Particular attention has been paid to understanding the relationships between the structure and the optical properties of these compounds. The materials have also been processed by incorporating them into polymer matrices, for example, to develop potential applications.
