Crown ether inclusion compound 3,4-difluoroanilinium di(methanesulfonyl)amidate–18-crown-6 (1/1) clathrate

In recent years, molecular-based ferroelectric materials have attracted widespread research interest due to their excellent performance. Among them, host-guest-type crown ether inclusion compounds composed of organic ammonium cations, crown ether molecules and corresponding anions have become a star component in the design of molecular-based ferroelectric materials because they are prone to order-disorder phase transitions. Many anions have been studied extensively as counter-ions, such as bis(trifluoromethanesulfonyl)amidate (TFSA
