dc.description.abstract | Highly efficient and long-living green thermally activated delayed fluorescence (TADF) organic light-emitting diodes (OLEDs) were developed using benzothienopyrimidine-4-benzonitrile acceptor-derived compounds as the TADF emitters. A molecular design merging the benzothienopyrimidine-4-benzonitrile acceptor with either indolocarbazole or diindolocarbazole was employed to prepare two TADF emitters, 5-(2-phenylbenzo [4,5]thieno [3,2-d] pyrimidin-4-yl)-2-(5-phenylindolo[3,2-a]carbazol-12(5H)-yl)benzonitrile and 2-(10,15-diphenyl-10,15-dihydro-5H-diindolo[3,2-a:3',2'-c] carbazol-5-yl) -5-(2-ph[4,5] thieno[3,2-d] pyrimidin-4-yl)benzonitrile (BTPDIDCz), as the green and greenish-yellow emitters. Among the two emitters, BTPDIDCz with the diindolocarbazole donor combined with the benzothienopyrimidine-4-benzonitrile acceptor demonstrated a high external quantum efficiency of 24.5% and 3 times longer device lifetime than the state-of-the-art green emitter. Thic work proposed the potential of benzothienopyrimidine-4-benzonitrile as the acceptor for long lifetime in TADF emitters. | - |
