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 1H NMR spectroscopy, electronic absorption spectroscopy and Isothermal Titration Calorimetry (ITC). In the case of Q, a 1:1 host-guest complex is favoured with on end of G initially embedded in the Q, although over time (48h), the Q shuttles along the chain such that it resides over the centre of G. For Q, a 2:1 host-guest complex is formed with the aromatic groups at each end of G buried in a Q cavity. The molecular structure of the inclusion complex having composition overall composition of Q.GH2.2Cl.14H2O has been determined, and clearly shows the insertion of the guest molecule with the host Q and it is localised therein by two N-H∙∙∙O hydrogen bonds.
