Résumé     
Using multinuclear copper iodide complexes as cross-linking agents in a polyurethane matrix, original photo-luminescent stimuli-responsive materials were synthesized. The intrinsic photoluminescence properties of the covalently incorpo-rated copper iodide complexes are thus transferred to the materials while retaining the beneficial characteristics of the polymer host. The transparent materials exhibit room-temperature phosphor-escence with emission switching properties by displaying luminescence thermochromism and solvatochromism. The lumi-nescence thermochromism is characterized by a change in the wavelength and intensity of the emission with temperature, and the vapochromic effect presents a contrasted response of extinction or exaltation according to the nature of the solvent of exposure. By combining the luminescence characteristics of photoactive copper iodide complexes with the ease of polymer processing, the application of these luminescent materials as phosphors in LED (light-emitting diode) devices was also demonstrated. The present study shows that the use of copper iodide complexes as cross-linkers in polymeric materials is a relevant strategy to design materials with enhanced functionalities in addition to their low cost and sustainable characteristics.
