"Making Materials that Make Twin Triplets from a Singlet"
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 Shockley–Queisser limit of 33 percent to 44 percent. 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. This talk will provide an overview on our approach to the design, synthesis, and evaluation of the materials.
Professor Campos' research group is interested in exploiting nanostructured materials for the development of advanced functional systems. They take advantage of macromolecular structures that can be finely tuned through molecular design and robust synthetic strategies. The interdisciplinary nature of the work allows the group to build strengths in synthesis, device fabrication, and fundamental design and characterization of the materials from form to function. Their research targets a multi scale approach to study fundamental properties of organic materials - from single-molecule electronics, to (macro)molecular function, and nanostructured materials. While these three sections are divided here, there is extensive cross-pollination in these research areas. The nature of their fundamental approach aimed toward understanding structure allows us to mold our materials for important applications in biology, engineering, physics, and processing.
