Molecular Structure of the Inclusion Complex of 5-[Perfluoro(2-isopropyl-1,3-dimethyl-1-butenyl)oxy]isophthalic Acid with Ethanol

Title compound has been found to form a 2:2 crystalline inclusion complex with ethanol, and X-ray crystal structure of the complex was determined. In the structure of the complex, four intermolecular hydrogen bonds are involved between the two host and two guest molecules. By using the complexation, extraction of ethanol from aqueous solution is demonstrated.
