一种OLED材料及包含该材料的有机电致发光器件
摘要：
本发明公开了一种新型OLED材料及其应用，所述新型OLED材料具有通式为：式(1)，其中，Ar选自C6‑C20芳基基团、芳胺基团或杂芳基基团；X为O或CMe2；R为氢或CN。本发明还公开了上述有机电致发光材料的制备方法及其应用。本发明的有机电致发光材料，具有较好的载流子传输效率及热力学稳定性、良好的成膜性、适合的分子能级、发光效率高的特点，可以作为蓝光掺杂材料，应用在有机电致发光领域中。
摘要（英）：

The invention discloses a novel OLED (organic light-emitting diode) material and an application thereof. The novel OLED material has a general formula shown in the description, wherein Ar is selectedfrom a C6-C20 aryl group, an arylamine group and a heteroaryl group; X is O or CMe2; R is hydrogen or CN. The invention also discloses a preparation method and the application of the OLED material. The OLED material has the characteristics of better carrier transport efficiency and thermodynamic stability, good film forming property, proper molecular energy level and high light-emitting efficiencyand can be applied in the OLED field as a blue light doping material.
