The excition bond in organic molecules: concepts for catalysis and solar cells

Organic materials offer a rich palate to be decorated with functional units in order to tune various properties. For example, the ability to generate multiple excitons from a single photon (singlet fission in molecular materials) has the potential to significantly enhance the photocurrent in single-junction solar cells, and thus raise the power conversion efficiency from the theoretical limit of 33% to 44%. However, there is a paucity of materials that undergo efficient singlet fission. Our group is interested in designing building blocks that are capable of generating triplet pairs in modular small molecules and polymers. In this vein, the reverse process of singlet fission – triplet fusion – provides the ability to upconvert low energy unabsorbed infrared photons into visible energy that can be used to improve the light absorption in solar cells. Here, we discuss our efforts into developing triplet fusion materials and the new potential applications. This talk will provide an overview on our approach to the design, synthesis, and evaluation of the materials for singlet fission and triplet fusion.

Professor Campos

Luis Campos is an associate professor in the Department of Chemistry at Columbia University. He was born in Guadalajara, Mexico, and moved at the age of 11 to Los Angeles, California. He received a Bachelor of Science degree in chemistry from California State University, Dominguez Hills, and a doctorate from the Department of Chemistry & Biochemistry at University of California, Los Angeles (UCLA). At UCLA, he was awarded a National Science Foundation (NSF) Pre-doctoral Fellowship, Paul & Daisy Soros Fellowship, and the Saul & Silvia Winstein Award for his graduate research in solid-state photochemistry. Switching to materials chemistry, he went to University of California, Santa Barbara, as a President’s Post-doctoral Fellow.

At Columbia, his group’s research interests encompass polymer chemistry, self-assembly, and organic electronic materials. To date, he has co-authored more than 80 articles and 12 patents; and he has received various awards, including the American Chemical Society Arthur C. Cope Scholar Award, Office of Naval Research Young Investigator Award, NSF CAREER Award, 3M Non-Tenured Faculty Award, I-APS Young Faculty Award, the Journal of Physical Organic Chemistry Award for Early Excellence, and the Polymers Young Investigator Award. In addition to these research accolades, Campos has been recognized for his pedagogical contributions by the Cottrell Scholar Award, Columbia University Presidential Teaching Award, and the Camille Dreyfus Teacher-Scholar Award. He is associate editor of Chemical Science.

Research

Professor Campos' group is interested in exploiting nanostructured materials for the development of advanced functional systems. Researchers take advantage of macromolecular structures that can be finely tuned through molecular design and robust synthetic strategies. The interdisciplinary nature of our work allows the group to build strengths in synthesis, device fabrication, and fundamental design and characterization of the materials from form to function.

With the immense potential to drive the technological economy in renewable energy resources and medicine, polymers have witnessed a surge of worldwide efforts to improve device architectures in plastic electronics as well as in vivo imaging and drug delivery systems. In all cases, it is widely accepted that materials displaying exceptional degrees of hierarchical ordering and involving robust synthetic strategies to produce pristine materials without impurities are highly desired. When combining the multiple levels involved in device fabrication and drug delivery vectors—from materials synthesis to the assembly of a functional system—the optimization of all variables is a laborious challenge. To tackle many of the issues associated with the development of thin-film transistors, plastic solar cells, and nanomedicine, our group is interested in the development of strategies for the fabrication of functional, highly ordered materials employing bottom-up and top-down manufacturing techniques.
