Thiophene Rust in Organic Electronics

The combination of Barbarella’s pioneering work on thiophene-1,1-dioxide (TDO) coupled with the development of Rozen’s reagent has allowed us to engineer materials for organic electronics. The controlled chemical oxidation of thiophene engages the lone-pair electrons in sulfur to bond with oxygen, generating TDO, a non-aromatic, diene-like building block with a strong dipole moment. When coupled with other conjugated systems, TDO lowers the LUMO of the resulting material. This talk will discuss the controlled chemical oxidation of polymers, in addition to the exceptional physical properties that arise from small molecules and polymers containing TDO. The importance of these materials in single-molecule electronics and third-generation solar cells will be emphasized.

Luis M. Campos is an Assistant Professor in the Department of Chemistry at Columbia University since 2011. He was born in Guadalajara, Mexico, and moved at an early age to Los Angeles, where he began his Californian public education. 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. Currently, his group’s research interests lie in polymer chemistry, self-assembly, and organic electronic materials. To date, he has published over 50 articles and 8 patents, and has been recipient of the NSF CAREER, 3M Non-Tenured Faculty, and the Cottrell Scholar Award.
