Pseudo-polyrotaxanes based on a protonated version of the 1,2-bis(4,4'-bipyridinium)ethane-24-crown-8 ether motif.
Protonated 1,2-bis(4,4'-bipyridinium)ethane axles and dibenzo-24-crown-8 ether wheels thread to form [2]pseudorotaxanes which associate in the solid state to form pseudopolyrotaxanes by hydrogen bonding or pi-stacking.
