Figure 15. (A) Chemical structures of C16 and C17, and chiral ditopic guests (R,R)-50/(S,S)-50; (B) the most energy-minimized structures for a three-layer model with double-helical form (left) and meso-like form (right); (C) CD spectra of C16 in the presence of a chiral guest (S,S)-50 (red lines) or (R,R)-50 (blue lines); and (D) VT CD spectra of C16 in the presence of (R,R)-50. CD: Circular dichroism; VT: variable temperature.
