Conductivity in metal-organic frameworks
Metal–organic frameworks (MOFs), are a class of crystalline materials whose crystal structure is made up from metal-containing clusters connected by multidentate organic linkers1,2. MOFs are attracting considerable attention due to the possible rational design of crystal structures of coordination frameworks with versatile metal ions and organic ligands. In principle, MOFs topologies along with intermolecular distances between various building blocks can be controlled using the fundamentals of reticular chemistry. This offers a great potential for tailoring MOFs properties for a wide scope of high-tech applications (high-capacity adsorbents, membranes, thin film devices, catalysis, biomedical imaging, etc.).
MOFs have traditionally been used for gas storage and separation, and much less attention has been devoted to their electronic properties3. This has changed in the past decade and MOFS with high electrical conductivity, charge carrier mobility and charge storage capacity became an emerging area of research. The physico-chemistry of inorganic (molecular) and organic (coordination polymers) conductivity are well understood by condensed matter researchers; however, this area is diverse and full of complexity. Thus, combination of both will represent a new paradigm.
Considering MOFS, conductivity can come from the metal, i.e. inorganic part ( metal chain, quantum dot), ligand, or incorporating in the pore. In addition, when we are speaking about electronic conductivity, it should be mentioned that electrons do not have an absolute monopoly on electrical conduction in solids. In literature still possible to meet a great uncertainty as to whether typical measurements allow researcher to conclude that conduction in a given m is due predominately to ions or to electrons. Many researchers have assumed that some of the MOFS can be treated as wide band gap semiconductors but other scientists have believed that most of known
