Abstract: | Herein we report an easy-to-synthesize 2]rotaxane, which incorporates two ionic monopyridinium stations and one 2,2'-bipyridine station as the shaft of the dumbbell-shaped component and a bis-p-xylyl26]crown-6 (BPX26C6) unit as the macrocyclic component. In this molecular shuttle, the BPX26C6 unit can be docked selectively on either the central 2,2'-bipyridine station or one of the two terminal pyridinium stations, and subsequently, returned to its shuttling molecular motion through the in situ addition of simple reagents (acid/base or metal ion/metal-ion-complexing ligand pairs). |
