封面专题说明了基于环糊精 (CD) 的 [3] 轮烷的酰化反应。在该反应体系中，一个[3]轮烷在两个CD单元上具有36个羟基，并且添加了过量的甲基丙烯酰酐，如背景所示。然而，当反应条件设计得当时，大约只有一个甲基丙烯酸单元（以黄色突出显示）被引入到一个CD环上，这可能是由于空间位阻的原因。因此，该产品可以用作[3]轮烷交联剂，以提供通过空间键合交联的网络聚合物。封面设计由赤江阳介设计。更多信息请参阅 Y. Akae 和 T. Takata 的研究文章。
The Cover Feature illustrates the acylation reaction of cyclodextrin (CD)-based [3] rotaxane. In this reaction system, one [3] rotaxane has 36 hydroxyl groups on two CD units, and excess of methacryl anhydride was added, as shown on the background. However, approximately only one methacryl unit (highlighted by yellow color) was introduced to one CD ring when the reaction condition was properly designed, probably owing to the steric hindrance. As a result, the product could be used as a [3] rotaxane crosslinker to afford network polymer crosslinked by through-space bonding. Cover design by Yosuke Akae.
