荧光金属配合物和二聚体已被合成并用于有机发光二极管。共轭分子配体的金属配合物具有很强的光致发光，在双层电致发光（EL）电池中显示出超过10 000 cd m（-2）的明亮发射。EL单元结构为[透明阳极/空穴传输层/发光层/阴极]。新合成的吡唑啉二聚体也是高荧光的，并且它们具有空穴传输倾向。因此，应用另一种类型的结构[透明阳极/发光层/电子传输层/阴极]以从吡唑啉衍生物获得发光。结果表明，一种吡唑啉衍生物与恶二唑类电子传输材料结合时，显示出最大值为1700 cd m（-2）的亮蓝色EL。
Fluorescent metal complexes and dimers have been synthesized and used for organic light-emitting diodes. The metal complexes with conjugated molecular ligands have strong photoluminescence, and showed bright emission of over 10 000 cd m(-2) in bilayer electroluminescent (EL) cells. The EL cell structure was [transparent anode/hole-transport layer/emitting layer/cathode]. The newly synthesized pyrazoline dimers are also highly fluorescent, and they have hole-transport tendency. Therefore, another type of structure [transparent anode/emitting layer/electron-transport layer/cathode] was applied to get emission from the pyrazoline derivatives. As a result, one pyrazoline derivative showed bright blue EL of 1700 cd m(-2) at the maximum when it was combined with an oxadiazole electron-transport material.
