Dual-channel control of ferroelastic domains in a host–guest inclusion compound

Abstract

By replacing [PF 6 ] − with the larger [TFSA] − , the phase transition temperature is increased from 305 K to 342 K in a host–guest inclusion ferroelastic crystal, [(3,4-DFA)(18-crown-6)][TFSA], which can realize dual-channel (thermal and stress) control of ferroelastic domains.
