摘要：
Liquid-crystalline polymers containing an oxadiazole moiety as an electron-transporting unit and a carbazole moiety as a hole-transporting unit in the same side chain were designed and synthesized to investigate electroluminescent (EL) properties. The synthesized polymers showed high fluorescence quantum efficiency. Furthermore, it was found that the luminescent polymers possessed bipolar carrier-transporting property. The single-layer organic light-emitting diode was fabricated to demonstrate EL emission. The device, ITO glass/the polymer/MgAg, exhibited intense blue emission with a maximum brightness of 30 cd/m(2) at 30 V.
