Abstract
Abstract Three new tetrakis(triarylamino)methanes have been designed and synthesized. These triarylamines have been shown to exhibit high glass-transition temperatures and optimal oxidation potential for achieving efficient OLEDs. The para -position of the aryl rings is blocked with electron-donating t -butyl or methoxy groups, which enhances the radical cation stability of these molecules—a highly desirable quality for hole transporters.
