C-undecylresorcin[4]arene 1 self-assembles to form the hexameric resorcinarene capsule C in the presence of H2O-saturated CDCl3. In blue are shown the bridging water molecules with H-bond-donating free valence toward the center of the cavity of C.

1H NMR spectra of TPFCBBMA 1 (A) and PTPFCBBMA (B) in CDCl3.

Confined wave behavior was observed in the H NMR spectra of 4e, 4g, and 4h in CDCl3 solution at 25 °C.
