Abstract

Thermally activated delayed fluorescence (TADF) emitters consisting of a xanthone acceptor unit and a para-, meta-linked tercarbazole donor unit were developed. The influence of the regioisomeric donoracceptor structures on their photophysical and TADF properties was studied. Blue organic light-emitting diodes employing these TADF emitters showed high external electroluminescence quantum efficiencies of up to 14.4% with suppressed roll-off characteristics.
