设计了一种分子转子，通过客体络合作用加速分子转子的旋转速度。乙酸酯客体与脲基团的结合使相邻的C-芳基-N-酰亚胺键的势垒降低2至4kcal/mol。这种行为与大多数分子转子相反，在大多数分子转子中，客体络合减慢旋转。
A molecular rotor was designed in which the rate of rotation is accelerated by guest complexation. The binding of an acetate guest to the urea groups lowers the barrier of the adjacent C-aryl-N-imide bond by 2 to 4 kcal/mol. This behavior is in contrast to most molecular rotors in which guest complexation slows rotation.
