Invited for this month's cover is Emilio M. Pérez from IMDEA Nanociencia in Madrid. The cover picture shows the supramolecular association of an ammonium guest to a crown‐ether host which is covalently attached to a SWNT. In our manuscript, we show that the corresponding “KPOW!!” would be significantly louder for the binding of the free species in solution, in the absence of the SWNT.

测量单壁碳纳米管附近的超分子复合物的稳定性。

来自马德里IMDEA Nanociencia的Emilio M.Pérez受邀参加本月的封面摄影。封面图片显示了铵客体与冠醚主体的超分子缔合，该冠醚主体与SWNT共价连接。在我们的手稿中，我们显示了相应的“ KPOW !!” 在没有SWNT的情况下，溶液中游离物质的结合会明显更大声。阅读其通讯全文，网址为10.1002 / open.202000018。
