Construction of supramolecular frameworks comprised of fully substituted cyclopentanocucurbit[5]uril and two substituted anilines.

• The host-guest interactions modes of fully substituted cyclopentanocucurbit[5]uril (CyP 5 Q[5]) with p -aminophenol and p -nitroaniline. • [Z n C l 4 ]2– ion participates in ion-dipole interactions with the outer surface of CyP 5 Q[5] to form supramolecular frameworks. • Two supramolecular frameworks have obvious holes and layered structure. The host-guest interactions modes of fully substituted cyclopentanocucurbit[5]uril (CyP 5 Q[5]) with p -aminophenol (G1) and p -nitroaniline (G2) were investigated by X-ray single crystal diffraction, 1H NMR spectroscopy, mass spectrometry, infrared spectroscopy and thermogravimetric analysis. The results shows that G1 and G2 interact with CyP 5 Q[5] to form host-guest complexes, which can enhance the thermal stability of G1 and G2. The crystal structure shows that G1 and G2 act on the carbonyl-fringed portals of CyP 5 Q[5] via ion-dipole interactions and hydrogen bond interactions, respectively. [ZnCl 4 ]2- ion participates in ion-dipole interactions with the outer surface of CyP 5 Q[5] to form supramolecular frameworks. [ABSTRACT FROM AUTHOR]
