Asymmetric thermally activated delayed fluorescence (TADF) emitters with 5,9-dioxa-13<i>b</i>-boranaphtho[3,2,1-<i>de</i>]anthracene (OBA) as the acceptor and highly efficient blue-emitting OLEDs

Abstract

With 5,9-dioxa-13<italic>b</italic>-boranaphtho[3,2,1-<italic>de</italic>]anthracene (<bold>OBA</bold>) as the acceptor, thermally activated delayed fluorescence (TADF) emitters adopting an asymmetric configuration can achieve highly efficient blue-emitting OLEDs.
