Preparation of octakis(3,6-anhydro)-γ-cyclodextrin and characterization of its cation binding ability
Abstract
Octakis(3,6-anhydro)-γ-cyclodextrin 3 has been prepared by the reaction of octakis (6-O-tosyl)-γ- Cyclodextrin with KOH; 3 shows a specific binding ability to alkali metal ions with larger ionic diameters, owing to its hydrophilic cavity which is similar to the layered crown ethers.
