摘要：

(Figure Presented) Building bridges: Imine bridges between the axle and ring components in rotaxanes allow simple rotaxane synthesis and a novel method for motion control to be developed. The submolecular mobility in this rotaxane-type assembly is regulated by the imine-bond formation/cleavage (see scheme). The relative abundance of the [2]rotaxane increases with decreasing temperature under dynamic equilibrium conditions. © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
