Nobel Prize in Chemistry 2025: Metal-Organic Frameworks (MOFs)
Stockholm, Sweden — The 2025 Nobel Prize in Chemistry has been awarded to three pioneering scientists for fundamentally revolutionizing material science. The prestigious award honors Susumu Kitagawa of Kyoto University, Richard Robson of the University of Melbourne, and Omar M. Yaghi of the University of California, Berkeley, "for the development of metal–organic frameworks (MOFs)."
The Royal Swedish Academy of Sciences lauded the trio for "creating new rules" in chemistry by designing a novel form of molecular architecture that promises custom-made solutions for some of the world's most pressing challenges.
The Breakthrough: MOFs, the Porous Super-Materials
The laureates' groundbreaking work centered on developing Metal-Organic Frameworks (MOFs), a class of highly porous, crystalline materials.
The innovation lies in their precise construction:
Metal ions (positively charged) function as robust cornerstones.
These are linked together by long organic (carbon-based) molecules functioning as struts.
Together, these components organize themselves into a well-ordered crystal structure containing vast, internal cavities. This structure is likened to a diamond filled with innumerable holes. By manipulating the building blocks, chemists can essentially "tune" a MOF to possess custom-made properties, such as capturing and storing specific substances.
A Journey of Innovation
The concept began in 1989 with Richard Robson, who successfully experimented with combining copper ions and a four-armed molecule to form a porous crystal. Although his initial constructions lacked stability, they laid the foundation.
Between 1992 and 2003, the field exploded due to advancements by the other two laureates:
Susumu Kitagawa demonstrated the flexibility of these frameworks and their capability to facilitate gas flow.
Omar M. Yaghi developed highly stable MOFs that could be chemically modified for specific functions, opening the door for industrial application.
Impact on the Future
MOFs have "enormous potential," according to Heiner Linke, Chair of the Nobel Committee for Chemistry. These custom-made materials are set to drive major transformations in areas such as:
Energy Storage: Developing more efficient ways to store hydrogen or methane for fuel.
Gas Separation and Capture: Crucial for filtering pollutants and potentially capturing greenhouse gases like carbon dioxide from the atmosphere.
Catalysis: Creating highly efficient catalysts to drive chemical reactions necessary for manufacturing and drug production.
The work of Kitagawa, Robson, and Yaghi is a testament to the power of molecular design, empowering chemists to create structures with precise properties for a sustainable and technologically advanced future.

Major Applications (Most Likely to be Asked in Descriptive Papers)
The development of MOFs unlocks "unforeseen opportunities" in crucial sectors:
Energy and Storage:
Hydrogen/Methane Storage: The massive surface area and porosity of MOFs make them ideal candidates for storing hydrogen (for fuel cell vehicles) or methane (natural gas) more compactly and safely than current methods.
Batteries: Certain MOFs are being explored for their ability to conduct electricity, potentially leading to safer and higher-capacity battery components.
Environmental Remediation and Gas Separation:
Carbon Capture: MOFs can be specifically tuned to selectively capture greenhouse gases, such as Carbon Dioxide (CO2), from power plant emissions or directly from the air, a major step in climate change mitigation.
Air Purification: They can be used to filter harmful pollutants, volatile organic compounds (VOCs), and toxic gases from the environment.
Water Purification: MOFs can selectively absorb heavy metals, dyes, or harmful ions from contaminated water sources.
Catalysis and Chemical Industry:
MOFs can act as efficient catalysts, using their large internal surface to drive specific chemical reactions much faster and more selectively than traditional materials. This has implications for manufacturing and drug synthesis.
Medicine and Drug Delivery:
The cavities can be loaded with therapeutic molecules or drugs. The frameworks can then be engineered to release the drug payload slowly and precisely within the body, functioning as a smart, targeted drug delivery system.
