Abstract
A phenylcarbazole-based compound is represented by Formula 1, and has superior electric properties and charge transport abilities, and thus is useful as a hole injection material, a hole transport material, and/or an emitting material which is suitable for fluorescent and phosphorescent devices of all colors, including red, green, blue, and white colors. The phenylcarbazole-based compound is synthesized by reacting carbazole with diamine. The organic electroluminescent device manufactured using the phenylcarbazole-based compound has high efficiency, low voltage, high luminance, and a long lifespan.
