<p>PURPOSE: A novel compound with improved lifetime, electrochemical stability and thermal stability and an organic light emitting element are provided to improve luminance efficiency. CONSTITUTION: A compound used in an organic light emitting element is denoted by chemical formula 1(A-L-B). In chemical formula 1: L is direct bond or a halogen group, an alkyl group, an alkenyl group, an alkoxy group, an aryl amine group, an aryl group, an aryl alkyl group, an aryl alkenyl group, a hetero aryl group, a carbazolyl group, a fluorenyl group, or an arylene group which is substituted or non-substituted with nitrile group; and A and B are independently denoted by chemical formulas 2-5. An organic light emitting element contains a first electrode, a second electrode, and one or more organic layers between the first and second electrodes.</p> |
