Abstract

The classic perception of MOFs as static crystalline structures has transited to flexible (i.e., dynamic metal–ligand interactions or hemilabile coordinate bonds), which has been acknowledged for contributing to unique physiochemical properties.[1] Thus, labile metal–ligand coordination can be dislocated by different stimuli without compromising the crystal structure of the material, in other words, the generation of transient open metal sites or semi-open metal sites.[2] The unique dynamic metal–ligand bonding of MFM-300(M) (MFM = Manchester framework material, M = different metals) is presented here, highlighting the exacting applications that were associated with such special behavior (i.e., description of complex NH₃ adsorption mechanisms, conversion of toxic H₂S to polysulfides for promising fabrication of lithium–sulphur batteries, heterogeneous catalysis and detection of SO₂).[3-6] Understanding that selected examples of MOFs are dynamic rather than static environments, can dramatically expand the reservoir of candidate MOF materials which can be contemplated for classic and new heterogenous catalytic applications. Thus, this talk aims to showcase the current advances in semi-open metal sites inherent to MFM-300(M) to inspire new investigations to be carried out to develop new applications of this promising family of MOF materials.
