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% 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. This talk will provide an overview on our approach to the design,
synthesis, and evaluation of the materials.
Luis M. 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 B.Sc. in Chemistry from CSU Dominguez Hills in 2001, and a Ph.D.
from the Department of Chemistry & Biochemistry at UCLA in 2006 working under the
supervision of M. A. Garcia-Garibay and K. N. Houk. At UCLA, he was awarded the NSF
Predoctoral 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 UCSB as a UC President's Postdoctoral Fellow to work
under the supervision of C. J. Hawker at the Materials Research Laboratory. At Columbia,
his group's research interests lie in polymer chemistry, self-assembly, and organic
electronic materials.
