Unlocking the potential of pore chemistry
Metal-organic frameworks (MOFs) are a class of hybrid crystalline materials built from the interconnection of metal nodes and organic ligands. Their ultrahigh porosity, and unprecedented chemical and structural tuneability have created interest in applications from storage and separation to catalysis. The EU-funded LIVINGPORE project will untap the potential of pore sequencing to control the conformational response of frameworks and encapsulated guests to lay definitive understanding on how reticular frameworks can be used to respond to (transformable) or select (transformative) specific molecular recognition patterns for cooperative selection in a crystalline solid. The project pursues a shift in the current perception of MOFs into unique porous materials capable of structural/functional responses closer to biological systems to enable distinctive applications currently unthinkable of, that will be initially demonstrated in separation and biocatalysis.
The conformational flexibility and biological function of proteins is dictated by the positioning of a few amino acids into specific arrangements linked by peptide bonds. We intend to implement this same principle of sequencing, essential to biology, to synthetic porous materials by encoding pore environments with atomic precision to control structural response and function. The road to this vision remains blocked by the lack of methodologies and understanding which is required to untap the value of pore chemistry in controlling the conformational response of frameworks and encapsulated guests. LIVINGPORE is structured around the complementary concepts of ‘transformable’ and ‘transformative’ porosity, that share the use of amino acid side chain chemistry and peptide bond rotations for selecting the conformational response and function of flexible frameworks (oligopeptide linkers) or flexible guests (small enzymes) by using programmed pore settings and mutants. We will develop both concepts in parallel by implementing a central high-throughput workflow that integrates computational and experimental routines for rational design and accelerated discovery. These synergic, multidisciplinary tools will be used to i) guide chemical synthesis, ii) evaluate structural response and iii) rationalize function, all required for going beyond what can be currently achieved with conventional methods. The central objective of this materials chemistry project is to lay definitive understanding on how reticular frameworks can be used to respond to (transformable) or select (transformative) specific molecular recognition patterns for cooperative selection in a crystalline solid. The long-term vision is a shift in the present perception of Metal-Organic Frameworks into unique porous materials capable of structural/functional responses closer to biological systems that enable distinctive applications currently unthinkable of, here initially demonstrated in separation and biocatalysis. |
