在钢轴承等机械设计中，对材料特性的基本了解为设计提供了不可或缺的基础。尽管碳氢环亚芳基已开始用于提供具有异常动态行为的独特超分子轴承，但对其的基本理解尚不成熟。现在报道了环亚芳基主体的独特性质：环状主体非常柔韧，可以跟踪椭圆体客体（即 C70 富勒烯）的取向变化。通过光谱和晶体学分析揭示了该复合物的独特结构，另外的理论研究通过揭示与无偏旋转运动相关的结构变化加深了我们的理解。
In the design of machinery such as steel bearings, a fundamental understanding of material characteristics provides an indispensable basis for the design. Although hydrocarbon cycloarylenes have started to be used for providing unique supramolecular bearings with anomalous dynamic behaviors, their fundamental understanding is immature. A unique property of the cycloarylene host is now reported: the cyclic host is so pliable that it tracks the orientational changes of the ellipsoidal guest, that is, C70 fullerene. Unique structures of the complex were revealed by spectroscopic and crystallographic analyses, and additional theoretical investigations deepened our understanding by revealing the structural changes associated with unbiased rotational motions.
