Anion-templated framework materials

Metal organic frameworks (MOFs) are currently an area of intense research interest, driven by a number of potential applications in gas storage, gas separation, and catalysis. These MOFs are three-dimensional polymeric structures built from organic linkers and metal nodes and containing large “empty” spaces, which can encapsulate guests.  In order to give charge-neutral MOFs, it is normally necessary to use negatively-charged ligands, and this significantly limits the types of guests that can be encapsulated, and hence the potential applications of these compounds.  We are interested in preparing framework materials that contain cationic ligands and anions as nodes, and in doing so, opening the door to a new range of potential applications.
