摘　　要：设计合成了一种N-苯基咔唑的衍生物:3-2-(3,3-二腈基亚甲基-5,5-二甲基-1-环己烯基)乙烯基-N-苯基-咔唑(PNCa-2CN)。PNCa-2CN的甲醇溶液光致发光光谱和固体膜光致发光光谱峰值分别位于598nm和660nm。以PNCa-2CN作为红色发光材料掺杂在A lq3中,制备了结构为ITO/NPB/A lq3:PNCa-2CN(5%)/A lq3/Mg:Ag/Ag的具有较高发光效率的红色有机电致发光器件,器件的发光峰值为600nm,在外加20V直流电压时达到2372cd.m-2的发光亮度,100mA.cm-2和20mA.cm-2其亮度分别为323cd.m-2和64cd.m-2,器件最大流明效率达到1.3 lm.W-1。A New N - phenyl - carbazole based red dopant 3 - 2 - （ 3,3 - dicyanomethylene - 5,5 - dimethyl - 1 - cyclohexylidene） vinyl - N - phenyl - carbazole （ PNCa - 2CN ） was designed and synthesized for use in red OLED. The photoluminescence and electroluminescence properties were examined. PNCa -2CN shows red photoluminescence with a peak wavelength at 660nm in the solid film and 598nm in solution. Red organic light emitting device （OLED） with PNCa-2CN was fabricated. OLED has a configuration of ITO/NPB/Alq3 ： PNCa -2CN （5 % ）/Alq3/Mg： Ag/Ag. The electrical and optical properties of the devices were studied.
