Integrative Self-Sorting: Construction of a Cascade-Stoppered Hetero[3]Rotaxane

W. Jiang, H. D. F. Winkler, C. A. Schalley— 2008

In this Communication, a competing self-sorting system containing benzo-21-crown-7, dibenzo-24-crown-8 and two secondary ammonium salts is constructed, which is then modified to achieve a hetero[3]pseudorotaxane with a specific sequence of wheels. With these two systems, we successfully demonstrate the concept of integrative self-sorting, and their relation. Furthermore, based on this self-sorting scheme, a hetero[3]rotaxane with an efficient stopper cascade has been synthesized.
