Nobel Prize in Chemistry Given for work on molecular architecture

The 2025’s Nobel Prize in Chemistry has gone to Susomo Catagawa, Richard Robson and Omar Yagi for the development of cavity materials that can store and release gases like carbon dioxide, known as the metal organic framework.

“The slight amount of such materials can almost be like a handbag of Hermune Harry Potter“The Nobel Committee chair for chemistry said Hinner Linky.” It can store a small amount of gas in large quantities. “

Now tens of thousands of different metal organic framework have been created. They have many potential applications to help COO catch₂ For chemicals in the chimneys forever and water harvesting from the air.

In the late 1980s, Richard Rubson was influenced by a diamond order structure at the University of Melbourne, Australia so that he could first create a metal organic framework. Robson found that it may be possible to use metal ions as nodes, and connect them with carbon -based, or organic, molecules.

When metal ions and organic molecules are mixed together, they collect themselves in the ordered framework. Although cavities in the diamond framework are small, the cavity in the metal organic framework can be very high.

The cavity in the organic framework of metal produced by Robson was full of water. It was Susomo Katgawa at Kyoto University, Japan, who first developed a framework that was so stable that it could be dried and managed to fill the empty cavity with gas.

“He showed that gases can be picked up, absorbed from this material, and can also be released from this material,” said Olof Ramstrom, a member of the Nobel Committee on Chemistry.

Katagawa also developed metal organic framework that changes the shape of gases or removal.

The University of California, Berkeley, managed to create even more stable framework by using lincles containing metal -ion clusters, and carboxylite groups containing oxygen, zinc and oxygen.

“This is an amazing framework because it was extremely stable,” said Remstrom. It was fully stable to 300 degrees Celsius. ” “But even more importantly, it has a huge area of ​​surface. So only a few grams of this unsafe material, almost Sub, like a small sugar cube, has a large pitch of football, which is several thousand square meters.”

Yagi also showed that the cavity in these substances can only be made larger, making the liners longer.

After these basic developments, the field was created very fast, Ramstrum said. “We see that the new metal organic framework is ready almost every day.”
