Chemistry-Physics 2019 Departmental Seminar Series: 'Advancing In Situ Dynamic Single-Crystal X-ray Diffraction'

12:15 p.m. 1:30 p.m. End Time
12:15 p.m. to 1:30 p.m. | Science and Mathematics Complex 173

Please join the Chemistry and Physics departments for the seminar "Advancing In Situ Dynamic Single-Crystal X-ray Diffraction," presented by Gage Bateman, Ph.D. candidate in the University at Buffalo's Department of Chemistry.

In situX-ray diffraction techniques provide the ability to monitor the change in the structure of crystals, such as metal-organic frameworks (MOFs), in response to changes in the local chemical environment surrounding the material. These methods reveal the location and concentration of guest species as well as the reorganization of the host framework as the contents of the void spaces are exchanged. Previous work in our group examined the dehydration of a flexible cobalt-based framework in the single crystalline phase using dry nitrogen gas as well as the exchange of the lattice waters with ethanol. Further in situ single crystal x-ray diffraction measurements performed on this cobalt-based framework reveal intriguing results for solvent exchange that show distinct differences with previous results seen ex situ. These results reveal a more complex, intricate system than previously believed.
