High Performance Solution-Processed PhOLEDs Samson A. Jenekhe, University of Washington, DMR 0805259 High-performance multilayered PhOLEDs fabricated by novel solution-processing method. Phosphorescent organic light-emitting diodes (PhOLEDs) are of growing industrial interest for applications in next-generation full-color display panels, flexible displays, and solid-state lighting. However, high-performance PhOLEDs are currently made by expensive vacuum deposition processes. We have successfully fabricated highly efficient polymer-based blue PhOLEDs by developing a novel, low-cost, solution-processing method and new solution-processable electron-transport materials such as TQB. The new results show the way towards high performance and low-cost multilayered PhOLEDs by solution-processing. They also provide new insights into solution-processing strategies that are broadly applicable to green, red, and white OLEDs as well as other multilayered organic electronic devices. TQB T.
