Abstract

The development of near UV-emitting materials will be presented. A novel ladder-like multiresonant thermally activated delayed fluorescence (TADF) compound was studied in the solid state. The compound shows narrow near UV-emission centered at 395 nm of optical excitation and at 410 nm in an OLED; however, the efficiency remains low. Photophysical studies reveal the presence of aggregate or excimer-like species that seem to provide an additional loss channel.
