摘　　要：The host-guest interactions between cyclopentanocucurbit-[6]uril(CyP_(6)Q[6])as host and six alkyl imidazolium hydrochloride as guests(g1,g2,g3,g4,g5,and g6)have been studied by various techniques,such as^(1)H NMR spectroscopy,isothermal titration calorimetry,mass spectrometry,and single-crystal X-ray diffraction analysis.The experimental results showed that CyP6Q[6]formed 1:1 inclusion complexes with each of guests g1-g6.The part of the guest entered the cavity of CyP_(6)Q[6]changes as the alkyl chain increases in length.It can be seen that the length of the alkyl chain plays a key role in determining the mode of host-guest interactions.
