Provided are a heterocyclic derivative and an organic electroluminescent device thereof, which relates to the field of organic photoelectric materials. The heterocyclic derivative of Formula I has high electron mobility and great hole blocking performance, and thus the organic electroluminescent device prepared by using the heterocyclic derivative as the electron transport region material, especially the hole blocking material, has low drive voltage and high luminous efficiency. The organic electroluminescent device can also include a hole transport region, and the hole transport region, especially the emissive auxiliary layer, contains the triarylamine compound of Formula II. Since the electron transport region and the hole transport region of the device can effectively balance carriers, which reduces the quenching of excitons and improves the recombination probability of carriers, the device shows low drive voltage and high luminous efficiency.
本发明提供了一种杂环衍生物及其有机电致发光器件,涉及有机光电材料领域。式 I 的杂环衍生物具有很高的电子迁移率和很好的空穴阻滞性能,因此使用该杂环衍生物作为电子传输区材料,特别是空穴阻滞材料制备的有机电致发光器件具有低驱动电压和高发光效率的特点。有机电致发光器件还可以包括空穴传输区域,空穴传输区域,尤其是发射辅助层,包含式 II 的三芳基胺化合物。由于该器件的电子传输区和空穴传输区能够有效平衡载流子,从而减少了激子的淬灭,提高了载流子的重组概率,因此该器件具有低驱动电压和高发光效率的特点。
