key to motion: A second‐generation molecular rotary motor, which contains a DB24C8 macrocycle ring incorporated into the lower stator half and a dialkyl ammonium ion attached to the upper rotor half, forms a [1]pseudorotaxane in less polar solvents such as CH2Cl2. In this self‐complexing system, acid–base‐controlled threading–dethreading movements can be utilized to unlock or lock the molecular motor
运动的关键:第二代分子旋转电机,其在下定子半部中包含一个DB24C8大环环,并在上转子半部中连接了一个二烷基铵离子,它在极性较小的溶剂(例如CH)中形成了[1]假轮烷2 Cl 2。在这种自复杂系统中,可以利用酸碱控制的穿线-脱线运动来解锁或锁定分子马达(见图)。
