The bisfuran-containing crown ether 8 has been incorporated, along with bis(paraquat-p-phenylene), into a catenane 2.4PF 6 using a self-assembly approach. The presence of the furan units in 8 has a disruptive influence upon the hydrogen bonding interactions involving this crown ether receptor and the paraquat dication. The perturbation of the hydrogen bonding interactions within the furan-containing catenane 2.4PF 6 results in changes in the dynamic properties of the relative ring motions compared with those observed for the molecular components of the catenane 1.4PF 6 .
