摘要：

A main chain-type polyrotaxane was fabricated by employing a one-pot synthesis strategy from a pseudorotaxane monomer and an end-capping agent. Based on this polyrotaxane, a controllable molecular machine was furnished upon the external acid/base stimuli, and a reversible transition between linear and cross-linked polyrotaxane was achieved by the successive addition of [PdCl2(PhCN)(2)] and PPh3.
