The new triazine-based acceptor moiety, which has been not reported, was synthesized by 2 step Suzuki-coupling reaction. Two different donors were used to synthesize thermally activated delayed fluorescence emitters, and they were 9H-carbazole (Cz) and 3,6-di-tert-butyl-9H-carbazole (tCz). These emitter materials were evaluated using unipolar host in OLED device. Cz derived emitter showed higher external quantum efficiency than the tCz derived emitter as green emitters.. This work demonstrated that newly synthesized triazine-based acceptor moiety was effective in green thermally activated delayed fluorescent organic light-emitting diodes. |
