Non-doped organic light-emitting diodes based on phenanthroimidazole-triphenylamine derivatives with a low efficiency roll-off of 9% at a high luminance of 10 000 cd m −2

Simultaneously achieving high exciton utilization efficiency ( η S ) and a low efficiency roll-off at high brightness is challenging for fluorescent organic light-emitting diodes (OLEDs). In this work, we tried to realize this goal by constructing “hot exciton” materials by fine-tuning the lowest tr...
