The physical–chemical properties of guest molecules confined within a zeolite framework host are known to be strongly affected by the confinement effects exerted through noncovalent host–guest interactions. On the basis of synchrotron time-resolved powder diffraction measurements and the Landau theory of ferroelastic phase transitions, we provide in this work evidence for the strong coupling existing between the thermodynamic properties of organic molecules (toluene, 1,2-dichloroethane, methyl-tert-butyl-ether) adsorbed within the ZSM-5 zeolite and the lattice strain driving the monoclinic-to-orthorhombic (ferroelastic-to-paraelastic) phase transition which controls connectivity and diffusivity in the zeolite framework.

Abstract

The physical–chemical properties of guest molecules confined within a zeolite framework host are known to be strongly affected by the confinement effects exerted through noncovalent host–guest interactions. On the basis of synchrotron time-resolved powder diffraction measurements and the Landau theory of ferroelastic phase transitions, we provide in this work evidence for the strong coupling existing between the thermodynamic properties of organic molecules (toluene, 1,2-dichloroethane, methyl-tert-butyl-ether) adsorbed within the ZSM-5 zeolite and the lattice strain driving the monoclinic-to-orthorhombic (ferroelastic-to-paraelastic) phase transition which controls connectivity and diffusivity in the zeolite framework.
