(a) Values of [θ]222 for specifically sited single Lys+ guests within the series 2 host at 2 °C (blue), 25 °C (orange), and 60 °C (magenta) at neutral pH in pure water. The solid lines correspond to values of [θ]222 for the host. (b) Values of [θ]222 for spaced pairs of Lys+ guest triplets within this host at 2 °C (blue), 25 °C (orange), and 60 °C (magenta). The following helical propensities are assigned at 2 °C: for (a), single substitutions at sites 4, 10, and 16, wLys[2] = 0.54, 0.70, ≥ 1.1. For the left-to-right triple substitutions of (b), <wLys[2]> = 0.53, 0.56, 0.40, 0.37, 0.43. For these, the helicity rank order is thus: (i, i ± 5) > (i, i ± 1) > (i, i ± 2) ≥ (i, i ± 4) > (i, i ± 3).
