MS-20: Dynamic frameworks
Invited: Hoi Ri Moon (Republic of Korea), Yao Chen (China) | ||
| Session Abstract | ||
|
Dynamic behaviour and structural flexibility are important properties of extended frameworks, such as Metal-organic Frameworks (MOFs), and in porous solids composed of molecular materials, like Metal-organic Polyhedra (MOPs) and Porous Organic Cages (POCs). In extended materials this can be realised as breathing or stimulus-response, providing access to unexpected porosity or sensing behaviour. For molecular materials, which lack strong bonding between components, structural transformations in response to sorbents can be profound, leading to advantageous sorption and separation processes. This session will examine the dynamic behaviour and structural flexibility of both molecular and extended porous frameworks, with a focus on phase transitions, which can be monitored by X-ray crystallography.
