Abstract
Calix[3]pyrrole exhibits fluxionality-induced effects on its 1H-NMR spectra. Calculations using DFT method reveal ring flipping-induced cage transformations with a low energy barrier. Molecular dynamics simulations confirm the continuous fluxional property. Computations elucidate an upfield shift of the N-H protons due to the shielding effects exerted by the π-electrons of the aromatic pyrrole rings. Halide anions form hydrogen bonds with N-H groups, effectively suppressing fluxional behavior.
