Invited for this month's cover are Iwona and Jean-François Nierengarten from the University of Strasbourg. The cover picture shows the structure of a [2]rotaxane building block bearing 3,5-bis(trifluoromethyl) benzenesulfonate (BTBS) stoppers. The BTBS moieties of this compound are good leaving groups allowing to perform stopper exchange by treatment with different nucleophiles to afford the corresponding rotaxanes with ester, ether or thioether stoppers.

本月的封面邀请到了斯特拉斯堡大学的 Iwona 和 Jean-François Nierengarten。该封面图片展示了一种带有 3,5-双（三氟甲基）苯磺酸（BTBS）塞的[2]轮烷砌块的结构。该化合物的 BTBS 部分是很好的离去基团，通过与不同亲核试剂反应，可以进行塞子交换，得到相应的带有酯、醚或硫醚塞子的轮烷。阅读全文，请访问 https://doi.org/10.1002/open.202000035。
