摘要：The interaction between the cucuribit[n]urils (Q[n]), where n = 6 or 7, and the guest N,N '-bis[4-(dimethylaminophenyl)methyl]butane-1,4-diamine (G) has been studied in aqueous solution by H-1 NMR spectroscopy, electronic absorption spectroscopy and Isothermal Titration Calorimetry (ITC). In the case of Q[6], a 1 : 1 host-guest complex is favoured with one end of G initially embedded in the Q[6], although over time (48 h), the Q[6] shuttles along the chain such that it resides over the centre of G. For Q[7], a 2 : 1 host-guest complex is formed with the aromatic groups at each end of G buried in a Q[7] cavity. The molecular structure of the inclusion complex having an overall composition of Q[6]center dot GH(2)center dot 2Cl center dot 14H(2)O has been determined, and clearly shows the insertion of the guest molecule with the host Q[6] and it is localised therein by two N-HMIDLINE HORIZONTAL ELLIPSISO hydrogen bonds.
