Abstract

Abstract A fluorine substituted triazine acceptor was developed for blue thermally activated delayed fluorescent (TADF) emitters. 9,9'-((6-(4-Fluorophenyl)-1,3,5-triazine-2,4-diyl)bis(2,1-phenylene))bis(3,6-di-tert-butyl-9H-carbazole) (FTrzTCz) was synthesized by connecting 4-fluorophenyltriazine with 3,6-di-tert-butylcarbazole at ortho position of a phenyl linker. The FTrzTCz emitter showed high efficiency of 18.5% and improved efficiency roll-off. The FTrzTCz also showed high quantum efficiency of 17.8% as an assistant dopant in the green fluorescent devices. The FTrzTCz worked well as a TADF emitter and an assistant dopant of hyperfluorescent devices by suppressed Dexter energy transfer.
