Abstract
Two different recognition sites, one a T-shaped 2,4,7-triphenylbenzimidazolium and the other a Y-shaped 2,4,5-triphenylimidazolium are combined to construct a rigid bistable [2]rotaxane molecular shuttle on which the position of a 24-membered crown ether macrocycle can be controlled by acid-base chemistry. Molecular shuttling in both the neutral and dicationic versions were studied.Entities:
