Study of host−guest interactions at various temperatures. a 2D NOESY spectrum (400 MHz, D₂O) of G1 + P5 (5.00 mM). The correlation signals between the host and guest were marked with rectangles. ¹H NMR spectra (400 MHz, D₂O) of G1 + P5 (5 mM) at b 25 °C, c 45 °C, and d 50 °C. Peaks belonging to de-threaded guest are marked with red arrows in c
