Fig. 6: NMR analysis for the assessment of ring shuttling in rotaxane 5.

Stacked 1H NMR (400 MHz, CDCl3, 298 K) of: a thread 6; b shuttle 5; c thread Cp-6 (see structure at the SI); d shuttle Cp-5. Signals related to the Diels–Alder adduct are colored in red. Signals related to the conjugated bis(enaminone) station are colored in green. Signals related to the succinamide stations are colored in orange. Signals related to the tetraamide macrocycle are colored in light blue. For lettering, see Fig. 5b.
