Abstract
| - Solid-supported multibilayers of the enantiomers of the cationic gemini surfactant 1, i.e., (2S,3S)-2,3-dimethoxy-1,4-bis(N-hexadecyl-N,N-dimethylammonium)butane dibromide (1a) and (2R,3R)-2,3-dimethoxy-1,4-bis(N-hexadecyl-N,N-dimethylammonium)butane dibromide (1b), have been studied by means of energy dispersiveX-ray diffraction. The effect of substrate on the orientation of the sample has been investigated. Dehydration/hydration kinetics of the samples under enviromental conditions has been followed. Furthermore, we havecharacterized the structural properties of the meso form, (2S,3R)-2,3-dimethoxy-1,4-bis(N-hexadecyl-N,N-dimethylammonium)butane dibromide (1c). The reported results indicate that the spontaneous self-assembliesof the meso form present different physical characteristics.
