Strategies to Improve Electrical Conductivity in Metal–Organic Frameworks: A Comparative Study

Strategies to Improve Electrical Conductivity in Metal–Organic Frameworks: A Comparative Study

2024 | Rajat Saha, Kajal Gupta, and Carlos J. Gómez García
The article reviews strategies to enhance the electrical conductivity of Metal-Organic Frameworks (MOFs), which are hybrid organic-inorganic materials with tunable porous structures and diverse applications. The low electrical conductivity of most MOFs is a significant barrier for their use in electronic devices. The review discusses both intrinsically and extrinsically conducting MOFs, highlighting the importance of charge transport pathways and the role of metal ions and organic ligands. Intrinsically conducting MOFs rely on the metal-ligand backbone for charge transport, while extrinsically conducting MOFs involve guest species within the framework. Key strategies include incorporating redox-active ligands, using extended conjugated organic ligands, employing hard/soft donor atoms, and utilizing mixed-valence metal ions. The article also provides detailed examples of conducting MOFs synthesized using these strategies, including their structural features, synthesis methods, and electrical conductivity measurements.The article reviews strategies to enhance the electrical conductivity of Metal-Organic Frameworks (MOFs), which are hybrid organic-inorganic materials with tunable porous structures and diverse applications.
