摘要
Pseudorotaxane type host-guest complex of a secondary ammonium salt and oxacalixcrown with the polyether linker as short as five ethylene glycol units was created. While an axle containing both ammonium and carbamate stations was installed in an oxacalixcrown-6-based [2]rotaxane through a threading-followed-by-stoppering approach, translocation of the oxacalixcrown-6 component of the [2]rotaxane from the secondary ammonium station to the carbamate station of the thread was achieved through blocking the amino moiety with a bulky Boc group.
