Abstract

Guest-mediated pore-shape modification of the metal-organic framework, Sc2BDC3 (where BDC = 1,4-benzenedicarboxylate), upon adsorption of n-pentane and isopentane is examined by single crystal X-ray diffraction at moderate pressures (50 – 1200 bar) using a newly developed sapphire capillary cell, which allows detailed crystallographic data to be obtained using a variety of liquids on flexible systems. For Sc2BDC3, rotation of the BDC linker that is responsible for the change in pore shape occurs at much lower pressures than previously reported, with distinct adsorption behaviour found between the pentane isomers.
