Cucurbit[6]-, cucurbit[7]-, and cucurbit[6]uril cavitands can be aligned along a spermine derivative axle in a well-defined, kinetically favored sequence at room temperature, and can undergo a reorganization toward a more stable [4]pseudorotaxane bearing three cucurbit[6]uril units upon thermally induced scrambling.
葫芦[6]脲、葫芦[7]脲和葫芦[6]脲穴番可以在室温下沿着精胺衍生物轴以明确的、动力学上有利的顺序排列，并且在热诱导的重排作用下可以向含有三个葫芦[6]脲单元的更稳定的[4]准轮烷进行重组。
