Metal-organic framework (MOF) materials are crystalline phases containing both inorganic and organic structural elements. They may be dense or nanoporous, and span the full range of dimensionalities from 0-D (molecular) to 3-D. A fascinating feature of MOFs, compared with inorganic and organic materials, is the possibility of tuning and controlling properties due to infinite diverse structural and chemical variability. Since MOF materials can exhibit the functionality of both inorganic and organic materials, they have a diverse range of properties and show potential for applications in a number of areas. Nanoporous MOF materials are of interest for hydrogen storage and CO2 sequestration and shape-selective catalysis, and dense MOF phases have eye-catching properties in areas that have traditionally been dominated by inorganic materials, e.g. negative linear compressibility and multiferroics behavior. In this talk, I will discuss the unique mechanical properties of a family of metal-formate framework materials, which exhibit properties that classical inorganics and organics rarely have.
