Organic Chemistry

 Research Focus - Organic Electronics My research program is devoted to the development of fundamental structure-function relationships in electronic polymers. The primary focus is to gain a deeper understanding of the effects of supramolecular organization on electronic and optical properties and how the organization of electroactive organic materials on the nanometer length scale can be optimized to control desired properties. Such fundamental work is combined with a focus on developing new materials for application in solar energy conversion. Polymer-Based Solar Cells Polymer-fullerene based photovoltaic devices have attracted a great deal of attention based on the potential for realizing low-cost, solution processable, and flexible solar cells. Recently, power conversion efficiencies of ~5% have been reported for the poly(3-hexylthiophene)/[6,6]-phenyl-C61 butyric acid methyl ester (P3HT:PCBM) bulk heterojunction solar cell. There is a great deal of interest in my group in developing new materials that will lead to polymer based solar cells with improved performance and enhanced stability. Work is focused on synthesizing new polymers and understanding how the chemical structure of the polymer influences electronic, physical, and materials properties. Supramolecular Assembly of Electroactive Polymers Semiconducting polymers have received a great deal of attention for potential applications in light emitting diodes (LEDs) and photovoltaic devices (PVDs). In such cases, electronic function is contingent on the interaction of two or more semiconducting materials. Specifically, in PVDs, donor and acceptor materials must work together in order to effectively harvest light, generate charge carriers, and transport charge. One of the most effective means for assembling two or more materials on the nanometer length scale is via the use of block copolymers, which are known to assemble in highly organized morphologies. However, a general platform for semiconducting block copolymers that allows organized assembly of two or more electroactive components has not been developed. As such, the development of new semiconducting block copolymers is a major focus of research in my group.
