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.[1]
  • To protect linoleic acid from oxidation.[2]
  • 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.[3]
