ZnCl2 has been used as a structural inducer in hydrochloric acid solution to construct three supramolecular frameworks of action utilizing cyclopentanocucurbit[6]uril (CyP(6)Q[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, (HNMR)-H-1 spectroscopy, and mass spectroscopy (MS). The results showed that G1 entered the molecular cavity of CyP(6)Q[6], CyP(6)Q[6] had portal and outer-surface interactions with G2, and G3 only acted on the outer surface of CyP(6)Q[6] with calcium ion coordination.
