An H-shaped [2]rotaxane with a biphenyl axle and a 24-crown-8 (24C8) macrocycle was inserted into the tetrahedral cavities of the isostructural fcu MOFs PCN-57, UiO-68-d₄, and UWCM-10. The resulting rotaxane containing MOFs UWDM-8, UWDM-9-d₄, and UWDM-10 have precise spatial arrangements of two different mobile components—a rigid rotor (tetramethylphenyl, phenyl-d₄, or tetrazine) and a rotaxane macrocycle (24C8). The mobility of these units was characterized by variable-temperature (VT) solid-state nuclear magnetic resonance (SSNMR). VT ¹³C SSNMR showed that the translational position of the macrocyclic wheel along the [2]rotaxane axle is dictated by the bulk and rotational orientation of the central rotor, while VT ²H SSNMR demonstrated that the dynamics of the rotor are influenced by the presence of the macrocycle.

将具有联苯轴和24-crown-8（24C8）大环的H形[2]轮烷插入同构fcu MOF PCN-57，UiO-68- d ₄和UWCM-10的四面体腔中。生成的含有MOF UWDM-8，UWDM-9 -d ₄和UWDM-10的轮烷具有两个不同的移动组分-刚性转子（四甲基苯基，苯基-d ₄或四嗪）和轮烷大环（24C8）的精确空间排列）。这些单元的迁移率通过可变温度（VT）固态核磁共振（SSNMR）来表征。VT ¹³ C SSNMR表明，大环轮沿[2]轮烷的平移位置取决于中心转子的体积和旋转方向，而VT ² H SSNMR表明，转子的动力学受存在的影响大周期的
