Supramolecular Self‐Assembly Modes of Cyclopentanocucurbit[6]uril and Aromatic Amines

ZnCl2 has been used as a structural inducer in hydrochloric acid solution to construct three supramolecular frameworks of action utilizing cyclopentanocucurbit[6]uril (CyP6Q[6]) as the host and (4‐aminophenyl)methanol (G1), 4‐benzylaniline (G2), and 4,4’‐diaminobenzophenone (G3) as guests. The structure was confirmed using X‐ray single crystal diffraction, 1HNMR spectroscopy, and mass spectroscopy (MS). The results showed that G1 entered the molecular cavity of CyP6Q[6], CyP6Q[6] had portal and outer‐surface interactions with G2, and G3 only acted on the outer surface of CyP6Q[6] with calcium ion coordination. In the hydrochloric acid solution, cyclopentanocucurbit[6]uril interacts with (4‐aminophenyl)methanol, 4‐benzylaniline, and 4,4’‐diaminobenzophenone, respectively, and forms three supramolecular frameworks induced by Zn2+.
