A C 3 ‐Symmetric tris‐urea derivative self‐assembles into either a discrete dimer or a supramolecular gel via continuous assembly, depending on the solvent used. In the less polar CDCl 3 , the discrete dimer was selectively formed, whereas in the more polar acetonitrile and acetone, a supramolecular gel was obtained. Additionally, the gel‐sol phase transition of an acetonitrile gel of the tris‐urea derivative responds bidirectionally to chemical stimuli.
