英文摘要	Hydrogen bonded arylamide foldamers have been introduced in switchable pseudo[2]rotaxanes and [2] rotaxanes, which also include a cyclobisparaquat(p-phenylene) (CBPQT(4+)) ring and a 'dumbbell' containing tetrathiafulvalene (TTF) and 1,5-dioxynaphthalene (DNP, for rotaxanes). The foldamer size changes through folding and unfolding serve as a steric handle to modulate the mechanical movement of the CBPQT(4+) ring along the dumbbell of the pseudo[2]rotaxanes and [2]rotaxanes. By varying the number of the repeating units in the foldamer, the kinetics of the solvent-dependent slippage/deslippage of pseudo[2]rotaxanes and the switching of the ring between TTF and DNP of the [2]rotoxanes can be tuned remarkably, with the time scope ranging from several minutes to several days, in twelve solvents of varying polarity, which have been confirmed by the H-1 NMR, UV-vis spectroscopy, and cyclic voltammogram experiments.
