An H-shaped [2]rotaxane comprising a bis(benzimidazole) axle and a 24-membered crown ether wheel appended with four trityl groups forms a highly crystalline material with enough free volume to allow large amplitude motion of the interlocked macrocycle. Variable-temperature (VT) H solid-state nuclear magnetic resonance (SSNMR) was used to characterize the dynamics of the [2]rotaxane wheel in this material.
一种 H 形[2]轮烷，由双（苯并咪唑）轴和带有四个三苯甲基基团的 24 元冠醚轮组成，形成具有足够自由体积的高结晶材料，允许互锁大环的大幅度运动。变温（VT）H 固态核磁共振（SSNMR）用于表征该材料中[2]轮烷轮的动力学。
