Japan’s Susumu Kitagawa became the country’s second Nobel winner this year on Wednesday, joining two other scientists in winning the chemistry prize for their roles in developing metal-organic frameworks.

The 74-year-old Kitagawa, a distinguished professor at Kyoto University, joined Richard Robson and Omar Yaghi in winning the award for creating "new rooms for chemistry,” said Hans Ellegren, secretary-general of the Royal Swedish Academy of Sciences.

“Metal-organic frameworks (MOFs) have enormous potential, bringing previously unforeseen opportunities for custom-made materials with new functions,” said Heiner Linke, Chair of the Nobel Committee for Chemistry.
