Abstract: A molecule containing azobenzene and cholesterol moieties (AzoChol) was synthesized,which forms supra-amphiphile with α-cyclodextrin (α-CD) based on host-guest interaction between azo group and α-CD.The supra-amphiphile AzoChol/α-CD self-assembled into vesicles in water,demonstrated by transmission electron microscopy (TEM),atomic force microscope (AFM) and confocal laser scanning microscope (CLSM).The azo group shows trans-cis photoisomerization by UV and visible light irradiation.Therefore,the supra-amphiphile AzoChol/α-CD is photo-switchable,leading to the disassembly and re-assembly of vesicles irradiated by UV and visible light alternately.The supra-amphiphilic structure of the new material may display potential applications in field for development of smart materials.

Key words: supra-amphiphile, self-assembly, host-guest interaction, azobenzene, photo regulation
