The 2025 Nobel Prize in Chemistry has been awarded to Susumu Kitagawa, Richard Robson, and Omar M. Yaghi for their groundbreaking work in the development of metal-organic frameworks (MOFs). These innovative materials are revolutionizing fields ranging from gas storage and separation to catalysis and drug delivery. Their ability to create highly porous structures with tunable properties has opened up unprecedented possibilities for addressing some of the world’s most pressing challenges.
The Royal Swedish Academy of Sciences recognized the trio’s pioneering efforts in designing and synthesizing MOFs, highlighting their potential to capture carbon dioxide, produce clean hydrogen fuel, and filter water. This year’s prize celebrates not just a scientific achievement but also the promise of a more sustainable future powered by molecular architecture.
The Architects of Molecular Space
Metal-organic frameworks represent a paradigm shift in materials science. Unlike traditional materials with fixed structures, MOFs are designed from the bottom up, combining metal ions with organic linkers to create highly ordered, porous frameworks. This modular approach allows scientists to tailor the pore size, shape, and chemical functionality of MOFs for specific applications.
Susumu Kitagawa: The Pioneer of Porous Coordination Polymers
Susumu Kitagawa, a professor at Kyoto University in Japan, is credited with laying the foundation for MOF chemistry. In the early 1990s, Kitagawa began exploring the concept of porous coordination polymers, which later evolved into the MOFs we know today. His work demonstrated the possibility of creating stable, crystalline materials with permanent porosity, challenging the conventional wisdom that such structures were inherently unstable.
Kitagawa’s early MOFs exhibited unique gas adsorption properties, sparking interest in their potential for gas storage and separation. His innovative synthetic strategies and meticulous characterization techniques paved the way for the development of a vast library of MOF materials with diverse functionalities.
Richard Robson: Expanding the Scope of Interpenetration
Richard Robson, an emeritus professor at the University of Melbourne in Australia, made significant contributions to the understanding and control of MOF architectures. Robson’s research focused on the phenomenon of interpenetration, where multiple MOF networks intertwine to form complex, three-dimensional structures. While interpenetration can sometimes reduce the porosity of MOFs, Robson demonstrated how to harness it to create materials with enhanced stability and selectivity.
Robson’s work on interpenetrated MOFs expanded the scope of MOF chemistry, revealing new possibilities for designing materials with tailored properties. His insights into the relationship between MOF structure and function have been instrumental in the development of MOFs for a wide range of applications.
Omar M. Yaghi: The Master of Reticular Chemistry
Omar M. Yaghi, a professor at the University of California, Berkeley, is widely regarded as the father of reticular chemistry, the art and science of stitching molecules together to create extended structures. Yaghi coined the term “metal-organic framework” and has been a driving force in the field’s rapid growth. His work has led to the development of MOFs with unprecedented surface areas and pore volumes, pushing the boundaries of what is possible in materials science.
Yaghi’s MOFs have shown exceptional performance in a variety of applications, including gas storage, carbon capture, and catalysis. He has also pioneered the development of covalent organic frameworks (COFs), a related class of porous materials constructed from organic building blocks. Yaghi’s vision and creativity have inspired a generation of scientists to explore the vast potential of reticular chemistry.
The Impact of Metal-Organic Frameworks
The development of metal-organic frameworks has had a profound impact on various fields, offering solutions to critical global challenges. Their unique properties make them ideal for applications ranging from energy storage to environmental remediation.
Gas Storage and Separation
One of the most promising applications of MOFs is in gas storage and separation. Their high surface areas and tunable pore sizes allow them to selectively adsorb specific gases, making them ideal for capturing carbon dioxide from power plants, storing hydrogen for fuel cell vehicles, and separating valuable gases from industrial waste streams. MOFs offer a more energy-efficient and cost-effective alternative to traditional gas separation technologies.
Imagine a future where carbon emissions from power plants are captured and converted into valuable products, or where hydrogen-powered vehicles roam the streets, emitting only water vapor. MOFs are making these visions a reality.
Catalysis
MOFs can also serve as catalysts for a wide range of chemical reactions. By incorporating catalytically active metal centers or organic ligands into the MOF framework, scientists can create highly efficient and selective catalysts for various industrial processes. MOF catalysts offer several advantages over traditional catalysts, including higher surface areas, tunable pore sizes, and the ability to encapsulate and stabilize reactive intermediates.
The use of MOFs as catalysts can lead to more sustainable and environmentally friendly chemical processes, reducing waste and energy consumption.
Water Purification
Access to clean water is a fundamental human right, yet billions of people around the world lack access to safe drinking water. MOFs offer a promising solution to this global challenge. Their porous structures can be used to filter out pollutants from water, including heavy metals, organic contaminants, and bacteria. MOFs can also be used to desalinate seawater, providing a sustainable source of fresh water.
The development of MOF-based water purification technologies could have a transformative impact on public health, particularly in developing countries.

Drug Delivery
MOFs are also being explored for their potential in drug delivery. Their porous structures can be loaded with drug molecules and then released in a controlled manner, providing targeted and sustained drug delivery. MOF-based drug delivery systems can improve the efficacy of drugs, reduce side effects, and enhance patient compliance.
The use of MOFs in drug delivery could revolutionize the treatment of various diseases, including cancer, diabetes, and infectious diseases.
Reactions to the Award
The announcement of the 2025 Nobel Prize in Chemistry has been met with widespread acclaim from the scientific community. Researchers around the world are celebrating the recognition of MOFs as a transformative technology with the potential to address some of the world’s most pressing challenges.
A “Harry Potter-Like” Innovation
Some have likened the impact of MOFs to a “magic handbag” from the Harry Potter series, capable of holding vast amounts of materials in a compact space. This analogy captures the essence of MOFs’ remarkable ability to store and separate gases, filter water, and deliver drugs with unprecedented efficiency.
The ability of MOFs to selectively capture and release molecules is indeed reminiscent of a magical feat, but it is grounded in solid scientific principles and ingenious molecular design.
A Testament to International Collaboration
The awarding of the Nobel Prize to scientists from Japan, Australia, and the United States highlights the importance of international collaboration in scientific discovery. The development of MOFs has been a global effort, with researchers from around the world contributing to the field’s rapid growth and diversification.
