A carbazole-based compound and an organic light-emitting device including the same, wherein the carbazole-based compound is represented by Formula 1:
wherein in Formula 1, at least one selected from R1 to R9 may be a group represented by Formula 2, and rings A and B are each selected from a phenyl or a naphthyl. When at least one compound represented by Formula 1 is included as a green fluorescent host in an emission layer of an organic light-emitting device, the example OLEDs may have improved efficiencies and longer lifespans compared to the organic light-emitting devices of the related art.
一种
咔唑基化合物和包括该化合物的有机发光器件,其中
咔唑基化合物由式 1 表示:
其中,在式 1 中,R1 至 R9 中至少有一个可以是由式 2 所代表的基团,且环 A 和环 B 分别选自苯基或
萘基。当至少一种由式 1 代表的化合物作为绿色荧光宿主被包含在有机发光器件的发射层中时,与相关技术的有机发光器件相比,本发明实例的有机发光器件可能具有更高的效率和更长的寿命。
