Provided are a condensed cyclic compound and an organic light-emitting device including the same. The material is represented by the formula A2-(A1)n1, wherein A2 may be selected from groups represented by Formula 2, A1 may be selected from groups represented by Formulae 2-1 to 2-4, and n1 may be an integer selected from 1 to 5:
Organic light-emitting devices manufactured using this material were found to have lower driving voltages, higher brightness values, higher efficiencies, and longer half-lifespans.
本发明提供了一种缩合环状化合物和包括其在内的有机发光器件。该材料由式 A2-(A1)n1 表示,其中 A2 可选自由式 2 表示的基团,A1 可选自由式 2-1 至 2-4 表示的基团,n1 可为选自 1 至 5 的整数:
使用这种材料制造的有机发光器件具有更低的驱动电压、更高的亮度值、更高的效率和更长的半衰期。
