Subphthalocyanine (SubPc)-stoppered [2]rotaxanes were synthesized for the first time. The rotaxane bearing unsubstituted SubPc as a stopper exhibited an equilibrium of slipping-on and slipping-off, whereas a perfluorinated SubPc stopper completely blocked slippage of the ring due to its slightly larger size. Kinetic studies revealed the Gibbs free energy of activation for the slipping-on and slipping-off processes. The optical properties of the rotaxanes, including photoinduced electron transfer, were also revealed.

不足酞菁的[2]轮烷：滑移的合成和尺寸/能量阈值。

首次合成了亚酞菁（SubPc）封端的[2]轮烷。带有轮烷的未取代的SubPc作为塞子表现出滑移和滑脱的平衡，而全氟化的SubPc塞子由于其尺寸稍大而完全阻止了环的滑动。动力学研究揭示了吉布斯活化自由能在滑移和滑移过程中的作用。还揭示了轮烷的光学性质，包括光致电子转移。
