摘要：

[GRAPHICS] A novel ambipolar spiro-configured D-A blue-light emitter bearing hole-transporting diphenylamino groups and electron-transporting phenylbenzimidazole groups was synthesized, characterized, and incorporated into an efficient single-layer organic light-emitting diode (OLED) device exhibiting blue-emission Commission International d'Eclairage (CIE) coordinates of 0.15 and 0.14, a turn-on potential of 4 V, a maximum brightness of 2800 cd/m(2) at 830 mA/cm(2) (19 V), and a maximum quantum efficiency of 0.53% (0.61 cd/A).
