Abstract

Abstract A very simple self-assembling system, which produces inclusion complexes with pseudorotaxane geometries, is described. The self-assembly of eight pseudorotaxanes with a range of stoichiometries–1: 1, 1: 2, 2: 1, and 2: 2 (host: guest)–has been achieved. These pseudorotaxanes self-assemble from readily available components–well-known crown ethers, such as dibenzo [24] crown-8 and bis-p-phenylene [34] crown-10, and secondary ...
