Quinoxaline-bridged resorcin[4]arene cavitands have the ability to undergo a triggered conformational transition from a contracted, vase state, to an open, kite state. This precisely defined conformational change makes them ideal for use as switches, receptors, or molecular grippers. However, to parlay the dynamic behavior of the cavitands into such advanced materials, it is important to create cavitands with more practical switching modes. Towards this goal, we developed quinone-based redox-switchable cavitands which can be applied in the area of nanorobotics, as molecular grippers.
