“…Single crystals of MOF-520 were loaded in a DAC with 4:1 methanol:ethanol as the pressure transmitting medium (PTM), and diffraction data were collected on beamline 12.2.2, from ambient pressure up to 2.82 GPa, at which pressure the crystal became amorphous. This amorphization is not unusual, in that the high pressure pushes the PTM into the pores, which degrades the long-range order of the crystal [72]. This invasion of PTM was quantified by examining the unit cell dimensions for an increase in volume, as well as determining the unassigned electron count using the program SQUEEZE [73].…”

Abstract:The more than a century-old technique of X-ray diffraction in either angle or energy dispersive mode has been used to probe materials' microstructure in a number of ways, including phase identification, stress measurements, structure solutions, and the determination of physical properties such as compressibility and phase transition boundaries. The study of high-pressure and high-temperature materials has strongly benefitted from this technique when combined with the high brilliance source provided by third generation synchrotron facilities, such as the Advanced Light Source (ALS) (Berkeley, CA, USA). Here we present a brief review of recent work at this facility in the field of X-ray diffraction under extreme conditions, including an overview of diamond anvil cells, X-ray diffraction, and a summary of three beamline capabilities conducting X-ray diffraction high-pressure research in the diamond anvil cell.

“…Previous studies of these materials under pressure had shown that the pressure transmitting medium could enter the pores of the framework (figure 5a), affecting its behaviour at high pressures [39]. Graham et al [37] have recently studied the prototypical MOF, MOF-5 [Zn 4 O(BDC) 3 , BDC = 1,4-benzenedicarboxylate] to 3.2 GPa on beamline I19 at DLS. In their study, the authors used diethyl formamide (DEF) as the pressure transmitting medium as more volatile media, such as alcohols, caused the single crystal to become polycrystalline (figure 5b).…”

Extreme conditions (EC) research investigates how the structures and physical and chemical properties of materials change when subjected to extremes of pressure and temperature. Pressures in excess of one million times atmospheric pressure can be achieved using a diamond anvil cell, and, in combination with high-energy, micro-focused radiation from a third-generation synchrotron such as Diamond, detailed structural information can be obtained using either powder or single-crystal diffraction techniques. Here, I summarize some of the research drivers behind international EC research, and then briefly describe the techniques by which high-quality diffraction data are obtained. I then highlight the breadth of EC research possible on Diamond by summarizing four examples from work conducted on the I15 and I19 beamlines, including a study which resulted in the first research paper from Diamond. Finally, I look to the future, and speculate as to the type of EC research might be conducted at Diamond over the next 10 years.

“…Beamline I19 has played a pivotal role in the recent development and exploitation of highpressure crystallographic methods and it has already contributed to landmark high-pressure investigations of well-known MOFs [30][31][32][33][34][35]. We have begun studies of the behaviour of our own more flexible MOFs, several of which possess outstanding gas storage or separation properties, at pressures of up to 100 kbar.…”

Large-scale central facilities such as Diamond Light Source fulfil an increasingly pivotal role in many large-scale scientific research programmes. We illustrate these developments by reference to energy-centred projects at the University of Nottingham, the progress of which depends crucially on access to these facilities. Continuing access to beamtime has now become a major priority for those who direct such programmes.
