on calixarenes threaded by dialkylammonium ions, which also represent the first examples of calixarene-based molecular shuttles, are reported. The base/acid treatment demonstrated that these systems act as molecular shuttles, which move between three sites on the axle. When small OMe groups are appended at the calix[6]arene lower rim an unprecedented inversion of its shuttling direction is observed,
据报道,基于杯芳烃被二烷基铵离子穿线的轮烷的第一实例,其也代表基于杯芳烃的分子穿梭的第一实例。碱/酸处理表明,这些系统充当分子梭,在轴上的三个位置之间移动。当较小的OMe基团附加在杯[6] arene下缘上时,观察到其穿梭方向发生了空前的反转,这是通过大环的圆锥到圆锥反转而发生的。
