The stability of a photoswitchable imine cage has been altered by irradiation with light. This facilitates the transformation of the cage upon application of external stimuli. A four-step opening/closing cycle has been achieved by controlling the rates of nuchleophile/imine exchange with an amine, which drives the system out-of-equilibrium. Furthermore, a light-induced cage-to-cage transformation has been demonstrated using the same principle.

动态笼基分子系统的光燃料转化

光照射改变了光开关亚胺笼的稳定性。这有助于在应用外部刺激时改变笼子。通过控制亲核试剂/亚胺与胺的交换速率，实现了四步打开/关闭循环，从而使系统失去平衡。此外，已经使用相同的原理证明了光诱导的笼子到笼子的转换。
