The Laboratory of Supramolecular and Macromolecular Photophysics and Photochemistry hosted artist Amélie Vignals to explore the phenomena of photoluminescence, fluorescence, and phosphorescence. From this collaboration between researchers and the artist emerged Tout s’éclaire, an immersive experience where light and matter engage in a dialogue. At the intersection of live performance, the arts, and science outreach, this journey unfolds through striking visual phenomena and invites visitors to question their perception of color, the origin of light emissions, and the presence of invisible light.
