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.
本发明公开了一种不对称的苯乙烯衍生物以及使用该衍生物制备的有机发光二极管。更具体地说,本发明提供了一种不对称的苯乙烯衍生物,通过合成一种具有式1所代表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,可以提供具有优越的热稳定性、改善的发光效率、改善的亮度和更长寿命的蓝色有机发光二极管,以及使用该衍生物制备的有机发光二极管。
