Abstract

Abstract Bistable rotaxanes are important design elements of molecular devices for a broad range of applications, such as controlled drug release, molecular rotary motors, and chemical sensors. The host–guest complexes of cucurbit [6] uril and 1, 4-bis (alkylaminomethyl) benzene were found to exhibit two stable binding modes with an unexpectedly high barrier between them. Their structural and dynamic properties, kinetic ...
