| abstract |
The present invention relates to a novel compound. Especially, the novel compound ensures easy hole injection properties by forming easily hole-injectable highest occupied molecular orbital (HOMO) by containing at least two arylamine groups when applied to organic light-emitting devices, and exhibits excellent hole transferability as well as high glass transition temperature (Tg). Additionally, owing to excellent molecular arrangement in thin film, mobility increases, and low driving voltage, low power consumption, high efficiency, and long lifespan can be achieved as well. |
