Chemistry and Biochemistry Announces Annual Celebration of Student Achievement

The Eighteenth Annual Department of Chemistry and Biochemistry’s Celebration of Student Achievement will be held virtually on Thursday, November 12, 2020.  The celebration begins at 2:00 p.m. with a plenary lecture entitled “The Role of Redox Doping in Organic Electronics and Opto-electronics” from Dr. Seth R. Marder, School of Chemistry and Biochemistry, School of Materials Science and Engineering, and Center for Organic Photonics and Electronics, Georgia Institute of Technology. See below for more details. The plenary lecture is open to the public and no registration is required. Join us in Microsoft Teams on November 12 at 2:00 p.m. .

The virtual Celebration of Student Achievement Awards Ceremony for Spring 2020 undergraduate and graduate chemistry majors follows the lecture at 3:30 p.m. We will recognize any alumni and donors in attendance as well. Please RSVP here by November 6. Contact or 330-672-2032 with any questions. The program can be found here.

“The Role of Redox Doping in Organic Electronics and Opto-electronics”, Dr. Seth R. Marder

Organic semiconductors and hybrid/organic materials have attracted interest for electronic applications due to their potential for use in low-cost, large-area, flexible electronic devices. Here we will report on recent developments pertaining to n-dopants that could impact the charge injection/collection processes in organic light emitting diodes, organic field effect transistors, and organic photovoltaic and hybrid organic/inorganic perovskite devices. I will highlight the application of n-doping for the development of electron injection layers for organic light emitting diodes (OLEDs), and their use for doping of electron transport materials which result in high conductivities and, in some cases, good thermoelectric performance. In the case of OLEDs, it will be shown that photoactivation (as illustrated in the cartoon at the right) can lead to stable doping of materials (i.e. the doping induced conductivity remains relative constant over hundreds of hours) beyond the expected thermodynamic limit, which would be predicted based on a assessment of the effective reduction potential of the n-dopant and the reduction potential of the electron transport material. We will also highlight some of the differences between approaches based upon “dimeric” dopants, vs. hydride donor dopants.

Dr. Seth R. Marder’s Bio:

Dr. Marder received his BA in Chemistry from MIT in 1978 and his Ph.D. from the U. of Wisconsin-Madison in 1985. After completing his postdoctoral work at the University of Oxford from 1985–1987, he moved to the Jet Propulsion Laboratory (JPL) at Caltech.

Marder has served on numerous advisory boards for journals and is the Founding Chair of the Editorial Board for the Royal Society of Chemistry premier materials journal, Materials Horizons.

Marder is a fellow of the: National Academy of Inventors, American Physical Society, Royal Society of Chemistry, Materials Research Society, Photo-Optical Instrumentation Engineers (SPIE), Optical Society of America and American Association for the Advancement of Science and a Member of the World Cultural Council.

He received an NSF Special Creativity Award Extension, the Lew Allen Award for Research, from JPL, the MRS Mid-Career Award, the American Chemical Society, Arthur C. Cope Scholar Award, Humboldt Senior Research Award and Georgia Tech’s Class of 1934 Distinguished Professor Award.

He has an H-index of >100, with > 58,500 citations (Google Scholar), has 39 granted patents, and served as a mentor for of ~250 students, postdoctoral and visiting researchers.
