Pressure and guest-mediated pore shape modification in a small pore MOF to 1200 bar

Abstract

Guest-mediated pore-shape modification of the metal–organic framework, Sc₂BDC₃ upon adsorption of n-pentane and isopentane is examined from 50–1200 bar. Rotation of the BDC linker responsible for the change in pore shape occurs at much lower pressures than previously reported, with distinct adsorption behaviour observed between pentane isomers.
