<p>PURPOSE: A bismuth compound is provided to have excellent light emitting ability, electron transfer ability, and hole transfer performance, thereby being used as a host material, an electron-transferring material, and a hole-transferring material. CONSTITUTION: A compound is represented by chemical formula 1. An organic electroluminescent device includes an anode, a cathode, and one or more organic material layers inserted between the anode and the cathode. At least one of the organic material layers includes the compound. The compound is included in one or more layers selected from a light-emitting layer, an electron-transferring layer, and a hole-transferring layer.</p> |
