Context: The Royal Swedish Academy of Sciences has awarded the 2025 Nobel Prize in chemistry to Susumu Kitagawa, Richard Robson and Omar M Yaghi for their work in the development of metal organic frameworks (MOF).

More on the News

• The journey began in 1989 when Richard Robson experimented with combining positively charged ions with a four-armed molecule, forming a crystal with numerous cavities. 
• Between 1992 and 2003, Susumu Kitagawa and Omar Yaghi advance the field as Kitagawa demonstrated gas flow through these frameworks and their potential flexibility, while Yaghi developed highly stable MOFs that could be modified for specific functions. 
• The trio have created molecular constructions with large spaces through which gases and other chemicals can flow. 
• In their constructions, metal ions function as cornerstones that are linked by long organic (carbon based) molecules. 
• Together, the metal ions and molecules are organized to form crystals containing large cavities.
