"Threading-followed-by-swelling": A new protocol for rotaxane synthesis
We describe the use of the new "threading-followed-by-swelling" protocol to synthesize molecular rotaxanes by modifying our previously reported "oxygen-deficient" macrocycle/dibenzylammonium ion molecular recognition system and using a cis-1-[(Z)-alk-1'-enyl]-2-vinylcyclopropane motif as the swellable terminal group.
