摘要：Novel side chain polypseudorotaxanes with cucurbituril (CB) threaded onto the side chains are synthesized from a water-soluble polymer and CB in water by simple stirring at room temperature. CB beads could move from the hexyl groups to the benzyl and a part of viologen units in the side chains of polymer when the molar ratio of CB to the monomer reaches from 1 to 2 as shown by 1H NMR studies, and it is considered that the hydrophobic and charge-dipole interactions of CB are the driving forces. The sizes of the polypseudorotaxanes with different molar ratio of CB to 4VBVHeP in aqueous solution increase with increasing the molar ratio of CB to 4VBVHeP as found by DLS and resonance light scattering, while the typical cyclic voltammograms and UV-vis data indicate that CB are not threaded in the viologen units of P4VBVHeP, and the oxidation reduction characteristic of the polymer is remarkably affected by the addition of CB.
