Abstract

Abstract Novel side chain polypseudorotaxanes with cucurbit [7] uril (CB [7]) threaded onto the side chains are synthesized from a water-soluble polymer and CB [7] in water by simple stirring at room temperature. CB [7] 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 [7] to the monomer reaches from 1 to 2 as shown by 1 H NMR studies, and it is considered that ...
