Structural and Electronic Correlations in Hybrid Materials: Perovskites under Pressure and O2-Binding Metal–Organic Frameworks
Understanding and controlling relationships between structural and electronic properties in materials enables their application toward important energy-related problems. Hybrid organic-inorganic materials, in particular, are attractive as highly tunable systems that can combine the strengths of molecules and extended solids. Here, I will detail research efforts in hybrid materials chemistry that are linked by this common theme of fundamental understanding and experimental control of structural and electronic correlations. I will illustrate how pressure—a valuable tool for modifying thermodynamic and transport properties—can engender dramatic compression-induced structural changes in halide perovskites, thereby altering and enhancing their electronic behavior. I will also describe how chemically reduced iron-pyrazolate metal–organic frameworks are capable of strong and selective adsorption of O2 over N2 at ambient (25 °C) or even elevated (200 °C) temperature, despite featuring coordinatively saturated iron centers.
Adam Jaffe, Ph.D., is a National Institutes of Health Postdoctoral Fellow in the Department of Chemistry at the University of California, Berkeley. He is studying O2 separation from air using metal-organic frameworks, and lithium adsorption and desorption in porous materials. He earned his doctorate from Stanford University, focusing his thesis on structural and electronic correlations in hybrid materials, high-pressure behavior opteolectronic properties, and energy-storage capabilities. He earned his AB in chemistry from Princeton University, and was also a Princeton Energy Grand Challenges Research Fellow, studying at Seoul National University, and a Research Intern in Science and Engineering at the University of California, Santa Barbara.
