title: Redox behavior of ferrocene-containing rotaxane: transposition of the rotaxane wheel by redox reaction of a ferrocene moiety tethered at the end of the axle.
abstract: A rotaxane with a ferrocene moiety at the axle terminus was prepared. The redox potential of the ferrocene moiety decreased by ca. 80 mV when the rotaxane had a crown ether wheel capable of moving on the axle. Thus, the stabilization of the oxidized state of the ferrocene moiety is assumed to accompany the transposition of the wheel component on the axle toward the ferrocene moiety. [reaction--see text]
