1H NMR spectra (THF-d8, 298 K, 500 MHz) of anion-induced switching motion of rotaxane-branched dendrimer G3. a G3; the mixture of G3 and TBAA, for each rotaxane unit: b TBAA (1 equiv); c TBAA (2 equiv); d TBAA (3 equiv); e TBAA (4 equiv); f TBAA (5 equiv); and the mixture obtained after adding NaPF6 to the solution in f, for each rotaxane unit: g NaPF6 (5 equiv); h NaPF6 (7 equiv); i NaPF6 (8 equiv); j NaPF6 (10 equiv)
