Shin, Dong Jin;Hwang, Soon Jae;Lim, Junseop;Jeon, Chae Yeon;Lee, Jun Yeob;Kwon, Jang Hyuk research published 《 Reverse intersystem crossing accelerating assistant dopant for high efficiency and long lifetime in red hyperfluorescence organic light-emitting diodes》, the research content is summarized as follows. A highly efficient deep-red hyper fluorescence device achieving long device lifetime was fabricated by adopting a newly designed 2,5-bis(12H-benzo[4,5]thieno[2,3-a]carbazole-12-yl)-3,6-di(9H-carbazol-9-yl)terephthalonitrile (12BTCzTPN) thermally activated delayed fluorescence (TADF) assistant dopant. The 12BTCzTPN was designed via donor modification of 2,3,5,6-tetra(9H-carbazol-9-yl)terephthalonitrile (4CzTPN) to increase reverse intersystem crossing (RISC) rate for fast up-conversion. The carbazole donor moiety was replaced with 12H-benzo[4,5]thieno[2,3-a]carbazole (12BTCz) donor, which induced a small singlet-triplet energy gap and large spin-orbit coupling via the heavy atom effect of sulfur, resulting in 4.5-times faster RISC rate than the 4CzTPN TADF mol. The addition of 12BTCzTPN as an assistant dopant to a deep-red hyper fluorescence device resulted in a device with a high external quantum efficiency of 19.9% and a long device lifetime of 1312 h at 3000 cd/m2, which is up to 90% of the initial luminance.
