The host–guest assembly of CB7 with a series of alkyl(trimethyl)ammonium (C n TA + ) surfactants of different chain lengths ( n =6–18) has been studied. The complexation behaviour was investigated by NMR spectroscopy, isothermal titration calorimetry and kinetics measurements. The combined results of these techniques provided evidence for the formation of 1:1 inclusion and 2:1 external complexes in the cases of C n TA + with n =12–18. The binding constants for the 1:1 complexes are independent of the alkyl chain length of the surfactant, whereas a relationship between K 2:1 and the chain length of the surfactant was found for the 2:1 complexes.
