elaboration of a novel strategy to instill molecules with well-defined folded secondary structures in solution.
3.2 Systematic Investigations of Oligorotaxane Foldamers
These remarkable results for the folded polyrotaxanes motivated us to undertake a
more detailed investigation of analogous monodisperse oligomers in order to shed
more light on the dynamics and secondary structures they adopt in solution. We
anticipated that a more complete understanding of the solution-state structures and
