Abstract

Abstract The formation of host/guest complexes between cucurbit [7] uril (CB7) and tetradecyltrialkylammonium bromide surfactants with trimethyl (C 14 TMA+), triethyl (C 14 TEA+), and tripropyl (C 14 TPA+) head groups was studied. Complexation was studied by ESI-MS, isothermal titration calorimetry (ITC), and NMR spectroscopy. The structure of the complexes is strongly dependent on the surfactant head group. Both 1: 1 and 2: 1 ...
