Grant period	2023-09-01 - 2025-08-31
Funding body	European Union
Call number	HORIZON-MSCA-2022-PF-01

Note: Metal-organic frameworks, MOFs, are porous organic-inorganic hybrid materials that hold the potential for developing new technologies to tackle some of the pressing global challenges such as pollution, climate change and energy crisis. Their typical low mass densities, high internal surface area, large pore volumes and facile chemistry makes them suitable for application in gas storage, filtration, extraction, catalysis and so on. Some MOFs are known to show a substantial degree of structural flexibility wherein the framework reversibly expands/contracts when subjected to external stimuli like pressure/heat/light or during absorption/desorption. This structural flexibility, if fully understood, can be used to enable the technological development of MOF-based recyclable filters, switchable catalysts, threshold sensors, stimulus-induced drug delivery systems with integrated key-lock functionality, compressible gas tanks and so on. However, the origin of this flexibility has not yet been sufficiently understood to enable the rational design of flexible MOFs. This research project aims to provide a conceptual understanding on the origin of this flexibility at the atomic regime by analysing all unique building units, topologies, and frameworks of all published MOFs to design a universally robust metric for predicting flexibility and mechanical properties of MOFs with the overarching goal of providing a theoretical methodology for the crystal engineering of flexible MOFs.
