For guest 1, 13.5 mg (0.0152 mmol); for guest 2, 9.80 mg (0.0157 mmol); and for guest 3, 9.5 mg (0.0152 mmol) were each dissolved separately in 1.4 mL host solution in MeOD (1 mM) and added stepwise to the host solution. A 1 H NMR spectrum is captured after every titration step, and the chemical shift change of the two host peaks at 6.46 ppm (aromatic CH) and 3.65 ppm (bridging CH2) are monitored. The shift change was plotted with supramolecular BindFit to obtain the binding constants. An extreme peak broadening of the CH2 peak is observable upon guest titration (especially for guest 3), indicating a decreased molecular movement of the host molecule, which is assumed to be a consequence of the guest binding causing restricted molecular movement.
