A deep-blue fluorescent emitter 9-(4-(10-phenylanthracene-9-yl)phenyl)-9H-carbazole (PhPC) has been synthesized and applied in organic light-emitting diode (OLED). The monochromatic device based on PhPC shows a deep-blue emission peaked at 436 nm and has CIE coordinates of (0.15, 0.05). The device has a maximum external quantum efficiency of 3.6% and a maximum current efficiency of 1.8 cd A−1. Performance of the deep-blue emitting OLED is among the best of reported non-doped fluorescence deep-blue organic light-emitting diodes (OLEDs) with a CIEy around 0.05. A fluorescent/phosphorescent (F/P) white OLED has been fabricated by using PhPC as a deep blue fluorescent emitter. The device shows maximum efficiencies of 27.6 lm W−1, 35.1 cd A−1, and a maximum EQE of 17.4% with CIE coordinates of (0.35, 0.43).
