Abstract
Three new tetrakis(triarylamino)methanes have been designed and synthesized . These triarylamines have been shown to exhibit high glass-transition temp eratures 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 mol ecules-a highly desirable quality for hole transporters.
