Abstract
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. More information can be found in the Research Article by Y. Akae and T. Takata.
