Abstract
We have previously reported a novel rotaxane synthesis based on imine-bond formation between an axle molecule and a ring molecule, for which we can control the subunit mobility through reversible inverconversion between imine-bridged rotaxane and [2]rotaxane. Here we report structural effects of axle and ring units on mobility control, and preparation of [n]rotaxanes by degenerating the imine-bridged pseudorotaxane.
