The hydroxy-bearing diamine guest, 1,3-bis(2-aminophenoxy)-2-propanol, was synthesized and characterized. The crystal structure of the inclusion complex of cucurbituril (Q[8]) with 1,3-bis(2-
aminophenoxy)-2-propanol was determined by X-ray diffraction analysis. The results showed that the Q[8] bound the guest to form an inclusion complex in a ratio of 1∶2, and intermolecular π-π interations existed between the benzene rings of the two guest molecules in the cavity of Q[8]. The interaction of the host-guest system was investigated by 1H NMR techniques and UV-Vis spectroscopy, showing a good agreement with the crystal structure of the host-guest complex.

Key words: 1,3-bis(2-aminophenoxy)-2-propanol, crystal structure, cucurbituril (Q[8])
