ABSTRACT: New triphenylamine-carbazole end-capped molecules were synthesized by a divergent approach using bromination and Suzuki cross-coupling reactions. All compounds showed an excellent electrochemical reversibility and a good thermal stability. They were fabricated as hole-transporting layers (HTLs) with the device configuration of ITO/HTL/Alq(3)/LiF:Al. A bright green emission from the Alq(3) layer with a maximum luminance of 7500 cd/m(2) was observed at 9.8 V and a low turn-on voltage of 3.4 V. (c) 2006 Elsevier Ltd. All rights reserved.
