应用

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.

A novel deconvolution method for energy-resolved reaction cross sections is applied to determine intrinsic gas-phase dissociation energies for non-covalent α-cyclodextrin host-guest complexes. M06-2X//M06-L/6-31+G(d,p) calculations reproduce the experimental results and enable us to quantify the contribution of intermolecular hydrogen bonding.
