On page 840, X. Ma and co‐workers explore the functional C 3 ‐symmetric benzene‐1,3,5‐tricarboxamide‐anchored diarylethene ( C 3 ‐BTE ) molecule, which can evolve into ordered superstructures with tunable morphological properties via alternative light stimuli. The molecule self‐assembles into microrods via synergistic H‐bonding and π‐stacking interactions in toluene. After UV irradiation, most long microrods disassemble. While irradiating the sample with visible light, the microrods regenerate reversibly. In addition, solvent‐induced morphological transitions are also observed when transferring C 3 ‐BTE between nonpolar toluene and polar or mixture solvents.
