Figure 2: ¹H NMR titration of DAB with β-CD and CB[6] in the molecular self-assembling process.

¹H NMR spectra at 400 MHz of (a) ADA‒CB[6] complex, (b) ADA, (c) ADA‒β-CD complex, and (d) β-CD‒ADA‒CB[6] complex in D₂O at 25 °C. Inset in (d): Magnified area of phenyl protons ([ADA] = 1.0 mM, [CB[6]] = 2.0 mM, and [β-CD] = 3.0 mM).
