A 1,2-Bisdithienylperfluorocyclopentene covalently linked to aggregative gelling moieties based on a synthetic aminoacid unit have been synthesized. This rationnally designed molecular target lead to the spontaneous organisation of nanosized fibers which in turn form a 3D-network. The photoinduced ring-closure process involved in the photochromism of diarylethene suppresses the self-assembling properties. The system reversibly reverts back to the Gel state upon Visible irradiation.
