A novel fluorene-containing compound and an organic electroluminescent device including an organic layer employing the same. The fluorene-containing compound has excellent electrical characteristics and an excellent charge transporting capability, and so can be used as a hole injecting material, hole transporting material, and/or emitting material that is suitable for all-color fluorescent and phosphorescent devices, such as red, green, blue, and white fluorescent and phosphorescent devices. Accordingly, an organic electroluminescent device employing the fluorene-containing compound has high efficiency, a low driving voltage, high brightness, and a long lifetime.
