Slip sliding away: foldamers can function as modular stoppers to regulate the slippage and de-slippage of pseudorotaxanes and the switching kinetics and metastability of bistable rotaxanes. By simply changing the solvent or the length of the hydrogen-bonded foldamer, the lifetime of the metastable co-conformation state can be increased dramatically, from several minutes to as long as several days.
折纸可以作为模块化的塞子，调节假轮烷的滑动和脱滑动以及双稳态轮烷的开关动力学和亚稳性。通过简单地改变溶剂或氢键折纸的长度，可以大大延长亚稳态共构状态的寿命，从几分钟延长到几天。
