Structural effects of ditopic azoprobe-cyclodextrin complexes on the selectivity of guest-induced supramolecular chirality

Benzo-15-crown-5 and dipicolylamine are contained as the binding sites in a ditopic azoprobe ( 15C5-Azo- n -dpa ). However, the selectivities of guest-induced supramolecular chirality for cations and anions were dramatically altered by a slight change in the spacer length of ( 15C5-Azo- n -dpa ) 2 -...

Description
Summary:Benzo-15-crown-5 and dipicolylamine are contained as the binding sites in a ditopic azoprobe ( 15C5-Azo- n -dpa ). However, the selectivities of guest-induced supramolecular chirality for cations and anions were dramatically altered by a slight change in the spacer length of ( 15C5-Azo- n -dpa ) 2 -γ-CyD complexes in water. Guest-induced supramolecular chirality: the guest ion selectivity was dramatically altered by a slight change in the spacer length of ( 15C5-Azo- n -dpa ) 2 -γ-CyD complexes in water.
