Outline of Final Research Achievements

Dynamic characteristics of macromolecular [2]rotaxanes (M2R) consisting of a polymer chain as an axle component and one crown ether as a wheel component were revealed to afford new rotaxane switch in which the wheel position in the M2R can be controlled. Furthermore, topology transformation of polymer chains which was connected by the rotaxane linkage have developed by the introduction of the polymer chain onto the wheel component of the M2R. Through the present study, dynamic response materials based on mechanical linkage, where microscopic change in rotaxane structure affects macroscopic polymer properties in response to the polymer topology, were established.
