Parking:

There is hourly parking on campus, follow the parking information on the link below. Hourly rate is $4/hour up to 4 hours. If you park 5+ hours you will be charged the $20 daily rate.  The recommend parking on-campus parking lots: Jefferson structure, McCarthy Structure, and lot 2 (next to Seeley G. Mudd building). There should be signs for "text to park" at the entrance, and guests can buy hours on their phone.

Unleashing the potential of novel deep-blue 2-coordinate Au TADF complexes with short radiative lifetimes as emitters in OLEDs

Jonas Schaab

ABSTRACT:

This presentation highlights emitter materials for OLEDs utilizing earth abundant coinage metals. Two-coordinate cMa complexes have emerged as promising emitter materials due to their high luminescent efficiencies and short radiative lifetimes. This talk will highlight advances achieved in the recent years as well as the performance of respective devices. A series of complexes will be used to exemplify the color tunability as well as control of the radiative lifetime to reduce the roll off in efficiency of OLED devices at high brightness. The presentation offers insights for designing new cMa derivatives with faster radiative rates, providing flexibility in tailoring excited state lifetimes.

Biography:

Jonas Schaab is a graduate student at the University of Southern California with seven years of experience in materials and inorganic chemistry research. His specialization revolves around blue OLED emitters, where he has developed novel thermally activated delayed fluorescence (TADF) emitters with ultrashort lifetimes (τ< 300 ns) and high photoluminescence efficiency.

Jonas received his Bachelor’s and Master’s in inorganic and physical chemistry from LMU Munich, laying the foundation of his broad analytical expertise like NMR and spectroscopy. He has three years of experience as a materials engineer, focusing on the fabrication and testing of thin films and OLED devices. His extensive work in advancing the field of OLEDs resulted in several publications in prominent journals, conference presentations, and patents.

Roll-to-Roll Flexographically Printed OLEDs

Dr. Whitney Gaynor

ABSTRACT:

OLED is widely known as the highest quality display on the market, used in flagship products such as high-end TVs and smartphones. Many of the early promises of OLEDs have been realized and commercialized, including their ultra-thinness and potential for flexibility. However, today's flexible OLEDs are still fabricated in much the same way as rigid OLEDs on glass. And most of the innovation in the field is still aimed at high-end consumer products. At Sinovia, we use roll-to-roll flexographic printing to fabricate bottom-emitting OLEDs suitable for use in segmented, indicator, and passive matrix displays at price points that can compete with incumbent LCDs and LED assemblies. This is enabled by our proprietary materials technology and our in-house process, along with some key supplier partnerships. In this talk, I will cover our core technology, our development status, applications of our displays, and our current work as we move toward mass production.

Biography:

Whitney is the CEO and co-founder of Sinovia Technologies, a Stanford University spinout working to realize roll-to-roll printed OLEDs based on flexographic printing. Over time, her role at the company has evolved from pure R&D in roll-to-roll processing and OLED stack development to include managing a small team, supply chain sourcing and partnerships, working with customers to define technology requirements, and general business development. She has served as PI for multiple U.S. government grant programs from the National Science Foundation and the U.S. Department of Energy, and now occasionally serves as a reviewer for those programs. She took Sinovia through Y Combinator in 2017 and has raised three rounds of venture funding to date.

Whitney's doctoral thesis work served as the basis for founding Sinovia and her first author peer-reviewed papers in the field of organic electronics have been cited over 1200 times. She holds an S.B. in materials science and engineering from MIT and a masters and PhD in materials science and engineering from Stanford University.
