 Metal organic frameworks, MOFs, are a new type of porous material that can be used for a variety of applications due to their unique properties such as high surface area, tailored functionality, and tunable pore size. They have been studied extensively since they were discovered in the early 2000s and their use in gas storage for renewable energy has become increasingly popular. The article discusses the characteristics of MOFs, their synthesis methods, and how they can be used to create breathing behaviors. It also explores the underlying mechanisms behind these behaviors and how they can be manipulated to optimize performance. This article was authored by Meiz Al-Amami, Hugh Done, and Chil Hong Chen.
