In this study, we synthesized dibenzo[22–30]crown ethers and dumbbell-like secondary ammonium salts having stoppers of varying bulk. These crown ethers formed pseudorotaxanes with the ammonium ions...

An efficient method for preparation of rotaxanes, involving hydrogen bonding guided self-assembly and diaryldiazoalkanes ester forming end-capping of pseudorotaxanes, is described. The end-capping reactions proceed under mild conditions and furnish t

We have synthesized two [2]rotaxanes, each possessing a (Z)-alpha-methylstilbene unit as one of its stoppers, in good yield through the photoisomerization of terminal (E)-alpha-methylstilbene units of dialkylammonium salts in the presence of the crow

A [2]rotaxane, having (Z)-alpha-methylstilbene as a stopper, is (1) synthesized in good yield by using a (E)- to (Z)-stilbene photoisomerization process, and (2) dissociated by reverse photoisomerization from (Z)- to (E)-stilbene.

Rotaxanes possessing a crown ether as a wheel group and oligo ethylene glycol units in the dumbbell group were synthesized using hydrogen bonding guided self-assembly and diphenyldiazomethane ester forming end-capping of pseudorotaxanes. The selectiv
