在此，演示了使用氢键客人的分子转子的控制。通过适当定位的苯酚取代基，N-芳基酰亚胺转子可以形成分子内氢键，催化旋转异构化过程。客人的加入破坏了氢键，提高了旋转势垒，使旋转速度减慢了两个数量级。
Herein, the control of a molecular rotor using hydrogen bonding guests is demonstrated. With a properly positioned phenol substituent, the N-arylimide rotors can form an intramolecular hydrogen bond that catalyses the rotational isomerization process. The addition of the guests disrupts the hydrogen bond and raises the rotational barrier, slowing the rotation by two orders of magnitude.
