<p>PURPOSE: A compound is provided to ensure heat resistance, hole injecting and transporting performance, and light emitting performance, and to be applied to one or more among a hole injection layer, a hole transport layer, a phosphorescent and fluorescent host of a light emitting layer, and a dopant. CONSTITUTION: A compound is denoted by chemical formula 1. An organic electroluminescent (EL) device comprises an anode, a cathode, and one or more organic layers inserted between the anode and the cathode. At least one of the organic layers contains the compound. The organic layers are selected from the group consisting of a hole injection layer, a hole transport layer, and a light emitting layer. The compound is used as a phosphorescent host and a fluorescent dopant of a light emitting layer.</p> |
