Abstract
Advances in energy research require novel hybrid materials (materials containing both organic and inorganic components) with synthetic control over physical and chemical properties. Hybrid materials lie at the heart of emerging technologies in fuel cells, solar cells, sensors, and carbon capture and sequestration. Many potential applications (i.e. membranes, sensors, catalytic coatings) that exploit the chemical and physical properties of MOFs will require thin or ordered MOF films. This proposal seeks to combine expertise and unique experimental resources at EMSL (SEM/EDX, SEM/FIB, TOF-SIMS, in situ micro-FTIR) with synchrotron based (APPES, STXM, XRD) experiments, imaging capabilities at the Molecular Foundry (Ellipsometry, AFM), and laboratory based (liquid-phase QCM-D, micro-Raman) to investigate hybrid material thin films produced via liquid layer-by-layer epitaxy. The objective is to enhance our understanding of and expertise in developing thin film hybrid materials for energy applications. The proposed work seeks to develop and characterize MOFs whose chemical and physical properties change with exposure to an external stimulus: i.e. adaptive or responsive MOFs. If the MOF can be designed to undergo a MOF can be designed that undergoes a structural change upon stimulation (i.e. electrical, pressure, temperature, water vapor, gas uptake, light) then this stimulus functions as an ON/OFF switch. Combined these facilities and expertise provide unprecedented capabilities to probe the bonding sites, competition for bonding sites, and structural changes under in situ conditions as a response to an external stimulus. This program builds upon existing collaborations and jointly enhances DOE capabilities in hybrid thin film materials, a scientific area of increasing importance for DOE.
