Over time, the zinc ions in MOF-5 (pink solutions) get replaced with cobalt ions, (blue solutions) demonstrating the dynamics of metal organic frameworks. Credit: American Chemical Society.
MOF’s have many potential apps: antimicrobial agents, H-storage materials and solar-cell components.
Despite their rigid-sounding name, MOF structures are also dynamic – much more so than previously thought. This discovery could lead to the synthesis of brand-new types of materials. As the name implies, MOFs are composed of networks of organic (carbon-based) compounds interspersed with metal ions. Many different combinations of metals and organic components exist, but much of what we know about these systems comes from a zinc and benzene di-acid framework called MOF5...
