制备了以苯乙烯基三苯胺衍生物（简称ＳＡ）为空穴传输层Ａｌｑ３为发光层的双层有机薄膜电致发光器件。还把不同厚度的口恶二唑衍生物（ＰＢＤ）加在ＳＡ和Ａｌｑ３之间制备了两种三层结构的有机薄膜电致发光器件，实现了ＳＡ的蓝色发光。进行了器件存放实验，发现器件在大气中有较好的稳定性。十个月之后，仍有较高亮度的发光。分析了不同器件中的电致发光光谱和电流电压、亮度电压关系。计算了它们的量子效率，三种器件的量子效率都在０．１％以上，对以铝为电子注入电极的器件而言这是比较高的。并从能级结构模型出发，分析了器件的各种性质 A double-layered organic thin-film electroluminescent device with styrene-based triphenylamine derivative (SA) as the hole transport layer Alq3 as the light-emitting layer was prepared. Two kinds of three-layer organic thin-film electroluminescent devices were also prepared by adding oxadiazole derivatives (PBD) with different thicknesses between SA and Alq3 to realize the blue luminescence of SA. Device storage experiments were carried out and found that the device has good stability in the atmosphere. Ten months later, there is still a higher brightness of light. The relationship between electroluminescence spectrum and current and voltage and brightness voltage in different devices was analyzed. Calculating their quantum efficiency, the quantum efficiency of the three devices are above 0.1%, which is relatively high for devices with aluminum as the electron injection electrode. Based on the energy level structure model, the various properties of the device are analyzed
