Resorcin[4]arene cavitands can be switched between a kite conformation, adopted in the dark, and a vase conformation, generated under visible light irradiation. The switching is triggered by the formation of a semiquinone radical anion through a photosensitizing process. The large conformational rearrangement of the cavitands resembles the mechanical switching occurring in some flowers that bloom open in the evening and close during the day (cover design: Ella Maru Studio). More information can be found in the Full Paper by V. García‐López, F. Diederich, et al. on page 11451.
