The magnitudes of a(H) could be predicted for three possible radical conformations in water ( Fig. 3C) and were compared to experimental values. It was demonstrated that the parameters of 5 fit very well to a dihedral angle of 120° between the aryl–C and N–O bonds (referred to as α in the following), which corresponds to structure C, whereas the dimethyl- and dichlorine-substituted species 6 and 7 likely adopt conformation A with α = 0° ( Fig. 3C).

When comparing the 1H-NMR spectra of resorcin[4]arene 1 with and without glutaric acid 2, different guest signals of 2 are found upfield-shifted. Additionally, integration yielded a host–guest stoichiometry of around 1 : 1, indicating six enclosed guest molecules. The extend of the encapsulation process was shown to increase with higher concentrations of glutaric acid and longer reaction times, which was readily observable due to the high sensitivity of the host aryl peak at 6.1 ppm. This supported the proposed encapsulation mechanism and additionally indicated a slowly occurring exchange mechanism at the expense of solvent molecules, in this case chloroform. Intramolecular self-inclusion was another possible interpretation of the data, but this could be discounted with the use of DOSY NMR. In case of this hypothetical event, the diffusion coefficients of 3 in acidic solution would have remained similar compared to the monomer, whereas the experimental data shows a strong decrease of this value. This observation could only be explained with oligomers (or polymers).A. Ustinov, H. Weissman, E. Shirman, I. Pinkas, X. Zuo and B. Rybtchinski, J. Am. Chem.
