Disclosed are asymmetric styryl derivatives and an organic light emitting diode prepared using the same. More particularly, there are provided asymmetric styryl derivatives that can provide a blue organic light emitting diode with superior thermal stability, as well as improved luminous efficiency, improved brightness, and extended lifetime, by synthesizing a novel thermally stable compound with a styryl structure represented by Formula 1, and using the compound as a dopant in an organic light emitting layer (EML) of a multilayered organic light emitting diode, and an organic light emitting diode prepared by the same.
本发明涉及不对称的苯乙烯基衍生物及其制备的有机发光二极管。更具体地,本发明提供了一种不对称的苯乙烯基衍生物,通过合成具有式1所表示的苯乙烯结构的新型热稳定化合物,并将该化合物用作多层有机发光二极管的有机发光层(EML)中的掺杂剂,可以提供具有优越热稳定性、改善的发光效率、改善的亮度和延长寿命的蓝色有机发光二极管。同时本发明还提供了制备该有机发光二极管的方法。
