Abstract: A pair of optical isomerism amphiphlic molecules L-C10HL(N-(4-decaoxygen- 2-hydroxybenzene methylene)-L-leucine) and D-C10HL(N-(4-decaoxygen-2-hydroxybenzene methylene)-D-leucine)were synthesized. It was found that these two compounds showed superior surface activity and aggregation capability at higher pH value, which is so different from the traditional carboxylate surfactants. Furthermore, the interaction of L-C10HL and D-C10HL with cyclodextrin was also investigated by fluorescence excitation spectrum and circular dichroism spectrum.

Key words: Chiral surfactant, Vesicle, Surface activity, Fluorescence spectrum,  Circular dichroism spectrum
