Keywords: alkenylbond; functional crown ether; stimuli-responsiveness; switchable rotaxane; Introduction
Along with the development of supramolecular chemistry, much attention has been paid to the design and synthesis of novel and complicated mechanical interlocked molecules (MIMs) [1][2][3][4
alkenyl units are reacted to generate polymers. On the other side, a naked alkenylbond is introduced in the para position of the aromatic stopper. In the presence of external acid–base stimuli, the macrocyclic ring could be driven back and forth along the linear thread. Deprotonation of the DBA site by
