An organic light-emitting device including a first electrode, a second electrode, and an organic layer between the first electrode and the second electrode and including an emission layer; wherein the organic layer includes a host first compound represented by Formula 1 and a fluorescent dopant second compound represented by Formula 2:
When the compound represented by Formula 1 includes a condensed cyclic substituent and the compound represented by Formula 2 includes a condensed cyclic core, the organic light-emitting device may have improved thermal stability, a lower driving voltage, and higher efficiency.
一种有机发光器件,包括第一电极、第二电极以及位于第一电极和第二电极之间并包括发射层的有机层;其中有机层包括由式 1 表示的宿主第一化合物和由式 2 表示的荧光掺杂剂第二化合物:
当式 1 所代表的化合物包括缩合环取代基和式 2 所代表的化合物包括缩合环核心时,有机发光器件可能具有更好的热稳定性、更低的驱动电压和更高的效率。
