Abstract

New stable WOLEDs based on π-extended azatrioxa[8]circulenes have been fabricated. Combining the own blue emission of the azatrioxa[8]circulenes with the yellow-green emission of the “m-MTDATA:azatrioxa[8]circulene” exciplex a broad visible region, from 400 to 700 nm, is covered. The so constructed WOLEDs exhibit a luminance exceeding 23 700 cd m−2 and an external quantum efficiency reaching 3%.
