Provided are a novel compound for an organic electronic material and an organic electroluminescent device using the same. The compound for an organic electronic material according to the present invention has high electron transport efficiency, thereby preventing crystallization at the time manufacturing of a device, and allows a layer to be easily formed, thereby improving current characteristics of the device, and thus an OLED device having a lowered driving voltage and improved power efficiency as well as superior luminous efficiency and lifespan characteristics as compared with the existing material can be manufactured.
An organic light-emitting device having low-driving voltage, improved efficiency, and long lifespan includes: a first electrode (110); a second electrode (190) facing the first electrode; a first layer (130) between the first electrode and the second electrode, the first layer including a first compound; a second layer (150) between the first layer and the second electrode, the second layer including a second compound; and a third layer (170) between the second layer and the second electrode, the third layer including a third compound; wherein the first compound does not include a nitrogen-containing heterocyclic group comprising *=N-*' as a ring forming moiety, and wherein the first compound, the second compound, and the third compound each independently include at least one group selected from groups represented by Formulae A to C:
一种具有低驱动电压、更高能效和更长使用寿命的有机发光器件包括第一电极 (110); 面向第一电极的第二电极 (190); 第一电极和第二电极之间的第一层 (130),第一层包括第一化合物; 第一层和第二电极之间的第二层 (150),第二层包括第二化合物;其中第一化合物不包括包含 *=N-*' 作为成环分子的含氮杂环基团,且第一化合物、第二化合物和第三化合物各自独立地包括至少一个选自式 A 至 C 所代表基团的基团:
