[2]Rotaxanes featuring minimal helical axles


α,ω-Stoppered perfluorous domains act as rigid and chiral linear helical elements in rotaxane constructs. Dynamic NMR shows modified ring dynamics over 4–orders of magnitude compared to hydrocarbon analogues, while vibrational-CD shows stopper-induced preferential axle chirality.
