Metal-organic frameworks guest properties

Figure 3.15 The structure of [Tb(btc)(DMF)2] nH20. (a) Each Tb center is connected to six other Tb centers through four ligands, (b) The 13.5 x 7.6 rectangle channels viewed down the c direction (Tb, black O, grey C, white H, omitted DMF and H2O guest molecules in (b) have been removed for clarity).

Metal-organic frameworks are largely used for their host-guest properties, such as gas adsorption, anion exchange and chemical separation, much like zeolites. The following section will deal with some of these aspects individually.

These and similar studies employing more complex organic molecules as guests prove distinct features of the corresponding framework, like extraordinary cavity size or adsorption properties. The loading of MOFs with metal-organic precursor molecules is effected by the combination of the functionality of the precursors to...
