Leveraging mixed-valency for the development of electrically conductive and porous hybrid materials
Abstract/Contents
- Abstract
- Hybrid inorganic-organic materials combine the synthetic tunability of organic molecules with the electronic diversity of inorganic coordination compounds. Specifically, I synthesized and characterized novel hybrid materials that are both electrically conductive and porous. Conductive and porous hybrid materials have shown potential for energy applications such as energy storage, gas sensing, and heterogeneous catalysis. Finding conductivity and porosity in a single material is difficult, since these properties are orthogonal and tend to oppose one another. Because of these challenges, much effort has been dedicated to developing more of these multifunctional materials. The work presented below describes efforts to leverage mixed-valency to induce electrical conductivity in porous hybrid materials. I utilized electronic, magnetic, and optical spectroscopies to characterize the properties of these new materials. To understand structure-property relationships, I used Rietveld refinement and pair distribution function analysis of X-ray diffraction data to elucidate these materials' structures. I discovered that oxidation of a new Prussian blue analogue creates a mixed-valence material and induces an insulator to semiconductor transformation. I observed a similar transformation in novel copper-azobispyridine metallopolymers, whose electrical conductivity and porosity can be turned on and off through electrochemistry. These same metallopolymers also display reactivity with nitrogen dioxide that drastically changes the electronic, magnetic, and optical properties of the metallopolymers. Lastly, I synthesized and characterized a class of porous and conductive copper dithiolene materials.
