Abstract
Metal-Organic Frameworks (MOF)s are crystalline materials in which metal ions or metal-ion clusters are linked by rigid organic molecules, creating a supramolecular network that has permanent porosity. Unwanted “guest” species, which can be solvent molecules or residual reactant, can be removed without structural collapse. Once a MOF is activated in this way, it provides a highly ordered, chemically tailorable structure that could serve as an active component of electronic devices such as sensors and light-emitting diodes, or be used for energy-harvesting or conversion. The vast majority of MOF research to date, however, focuses on “traditional” applications of microporous materials, such as gas storage and separations. This presentation will summarize our efforts to create hybrid MOFs, in which a “welcome guest,” i.e., one that we deliberately introduce into the pores, creates new functionality relevant to various electronic device applications or induces a measureable signal. Using this approach, we developed MOF-based materials for hydrogen storage, radiation detection, light emission, and thermoelectric devices.
