Matériaux photoluminescents multifonctionnels à base de clusters d’iodure de cuivre

Abstract : In the last years, mechanochromic luminescent materials which exhibit reversible modification of the emission wavelength in response to external mechanical stimuli have attracted great attention because of their potential applications in optical memory devices, pressure sensing systems, for instance. Indeed, due to their promising development, the number of reported pressure sensitive luminescent compounds has exploded in the five last years with examples based mainly on organic dyes. Examples of transition-metal complexes are comparatively limited and essentially based on gold and platinum metals. The developed research concern the study of the mechanochromic luminescent properties of molecular copper iodide clusters. Upon mechanical grinding, their photoemission properties are greatly modified. These compounds have the particularity of exhibiting both mechanochromic and thermochromic luminescence properties.
