摘要

Self-assembly vesicles have been made from a cyclodextrin(CD)supramolecular complex,which is cooperatively formed with natural beta-CD,1-naphthylammonium chloride(NA),and sodium bis(2-ethyl-1-hexyl)sulfo-succinate(AOT)by weak noncovalent interactions.In the complex structure,a NA molecule is included inside a beta-CD molecule while it is coupled with an AOT molecule on one side.The supramolecular structure and morphol- ogy of the vesicles were characterized by transmission electron microscopy(TEM)and dynamic light scattering(DLS),respectively.The mechanism of vesicle formation and transition is discussed along with the data obtained from induced circular dichroism(ICD) and UV/visible spectroscopy,polarized optical microscopy(POM),and ~1H NMR spectroscopy.Both the fabrication and the transition of vesicles are controlled by the inclusion equilibria and the cooperative binding of noncovalent interactions,which include the "key-lock" principle,electrostatic interactions,pi-pi stacking,and amphi-philic hydrophobic association.
