Redox Behavior of Ferroene-Containing Rotaxane:Transposition of the rotaxane Whell by Redox Reaction of a Ferrocene MoietyTethered at the End of the Axle

摘要

A rotaxane with aferrocene moiety at the axle terminus was prepared.The redox potential of the ferrocene moiety decreased by ca.80mV when the rotaxane had a crown ehter whell 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 whell component on the axlej toward the ferrocene moiety.
