Morris Chemistry – A European Journal DOI: 10.1002/chem.202100528 Diamond Proposal Number(s): [24028] Open Access Show Abstract ▼ Abstract: The size of single crystals of the metal-organic framework CPO-27-Ni was incrementally increased through a series of modulated syntheses. A novel linker modulated synthesis using 2,5-dihydroxyterephthalic acid and the isomeric ligand 4,6-dihydroxyisophthalic acid yielded large single crystals of CPO-27-Ni (~70 µm). All materials proved high crystallinity and phase pure through powder X-ray diffraction, electron microscopy methods, thermogravimetric, and compositional analysis. For the first time single crystal structure analyses were carried out on CPO-27-Ni. High BET surface areas and nitric oxide (NO) release efficiencies were recorded for all materials. Large single crystals of CPO-27-Ni showed a prolonged NO release and proved suitable for in situ single crystal diffraction experiments to follow the NO adsorption. An efficient activation protocol was developed, leading to a dehydrated structure after just 4 h, which subsequently was NO-loaded, giving a first NO loaded single crystal structural model of CPO-27-Ni.

I19-Small Molecule Single Crystal Diffraction	In situ single-crystal synchrotron X-ray diffraction studies of biologically active gases in metal-organic frameworks Russell M. Main , Simon M. Vornholt , Cameron M. Rice , Caroline Elliott , Samantha E. Russell , Peter J. Kerr , Mark R. Warren , Russell E. Morris Communications Chemistry 6 DOI: 10.1038/s42004-023-00845-1 Diamond Proposal Number(s): [29217] Open Access Show Abstract ▼ Abstract: Metal-organic frameworks (MOFs) are well known for their ability to adsorb various gases. The use of MOFs for the storage and release of biologically active gases, particularly nitric oxide (NO) and carbon monoxide (CO), has been a subject of interest. To elucidate the binding mechanisms and geometry of these gases, an in situ single crystal X-ray diffraction (scXRD) study using synchrotron radiation at Diamond Light Source has been performed on a set of MOFs that display promising gas adsorption properties. NO and CO, were introduced into activated Ni-CPO-27 and the related Co-4,6-dihydroxyisophthalate (Co-4,6-dhip). Both MOFs show strong binding affinity towards CO and NO, however CO suffers more from competitive co-adsorption of water. Additionally, we show that morphology can play an important role in the ease of dehydration for these two systems.	Mar 2023
