Metal–organic frameworks (MOFs) are microporous materials composed of metallic nodes and organic ligands. Remarkably, just several days ago (October 8, 2025), the Nobel Prize in Chemistry was awarded to three distinguished pioneers in MOF research—Susumu Kitagawa, Richard Robson, and Omar M. Yaghi—an inspiring milestone for the entire MOF community.
In 2015, the first-ever MOF glass, derived from a zeolitic imidazolate framework (ZIF) known as ZIF-4 [Zn(C₃H₃N₂)₂], was reported. In the same year, the first coordination polymer glass was also discovered. Since then, extensive efforts have been dedicated to exploring and developing MOF glasses. In this talk, I will chronologically discuss the advancements in understanding the structure and functionalities of MOF glasses. I will share new insights into phase transitions in MOFs and examine how structural features govern the properties and functionalities of selected ZIF glasses. Finally, I will outline the key challenges and prospects for MOF glass research, with particular emphasis on their emerging potential applications. |
