Application:

α-Cyclodextrin can be used:
• As a ligand in the complexation of nonionic surfactants and polyethylene glycols. α-cyclodextrin shows strong interaction with the surfactants that contains no benzene group.
• To protect linoleic acid from oxidation.
• In the synthesis of binuclear copper(II) complexes with cyclodextrins, which can be further used as a template for the preparation of copper nanoparticles incorporated on mesoporous silica.
