Solution-processable orange-red thermally activated delayed fluorescence emitters with 3,6-disubstituted carbazole for highly efficient OLEDs with low efficiency roll-off

Abstract

Two orange-red TADF emitters, employing dicyanopyrazino phenanthrene as the acceptor and 3,6-disubstituted carbazole as the donor, were developed for use as high-efficiency solution-processed OLEDs with a low efficiency roll-off.
