Post-Synthetic Modification of a Metal-Organic Framework at
High Pressure

Metal-organic frameworks (MOFs) are relevant to a wide range of practical applications, from gas storage to shock-absorbing armour, owing to their diverse chemical compositions, structures, and porosities. The properties of MOFs can be tuned in the solid state by post-synthetic modification, which traditionally involves soaking crystals of the framework in a solution of reactant to promote reaction or exchange at the metal or ligand. Post-synthetic modification is advantageous over de novo routes as there is no need for crystallisation. However, it is limited by the requirement for the reactant to enter the framework pores, rendering many MOF-reactant systems inert due to size-exclusion.
Here, it is shown that high-pressure can be used to force reactant into the frameworks pores to promote post-synthetic modification. Hydrostatic compression of a single crystal of the newly-synthesised, MIL-53(Sc)-EDB (where ML = Matériaux de l’Institut Lavoisier and EDB = ethynylenedibenzoate) in a pressure-transmitting medium of methanol to 0.7 GPa results in post-synthetic exchange of a bridging hydroxide ligand for a bridging methoxide, which changes the shape and hydrophobicity of the framework pores. The reaction can be followed directly by in situ high-pressure single crystal X-ray diffraction.

X-rays: Empowering Energy Research at Curtin University
Dr Terry D. Humphries

Fuels and Energy Technology Institute,
Curtin University

The Hydrogen Storage Research Group (HSRG) at Curtin University is a team specialising in the development of energy storage materials. Current projects include the development of materials for thermal energy storage, solid-state hydrogen storage, and solid-sate battery materials. These fundamental research projects, and consequential upscaling experiments, require advanced analytical techniques to determine the physical properties of compounds that range from nano-scale to bulk samples. X-ray based techniques offer the HSRG a substantial range of capabilities that facilitates the development of future energy storage media.
This presentation will elucidate how the HSRG has employed data collected using various X-ray techniques in their research. This includes the determination of reaction pathways as a function of temperature using in-situ powder X-ray diffraction (PXD); crystal structure determination and quantitative phase analysis using PXD; structure determination using single crystal X-ray diffraction; pore size distribution using small angle X-ray scattering (SAXS); and X-ray photoelectron spectroscopy (XPS).
