PURPOSE: A blue electroluminescent polymer and an organic electroluminescent device using the polymer are provided, to improve the luminescence efficiency, the brightness, the lifetime and the stability. CONSTITUTION: The blue electroluminescent compound is represented by the formula 1, wherein Ar is an aromatic group of C6-C26 or a heteroaromatic group of C4-C20 and can be substituted with an alkyl group of C1-C12, an alkoxy group of C1-C12 or -N(R')(R') (wherein R' and R' are independently H or an alkyl group of C1-C12); X is O, CH2 or S; R is H, a linear or branched alkyl group of C1-C12, an alkoxy group of C1-C12, a cyclic alkyl group of C3-C12, or an aromatic group of C6-C14, and the aromatic group can be substituted with an alkyl group of C1-C12, an alkoxy group or -N(R')(R') (wherein R' and R' are independently H or an alkyl group of C1-C12); and n is 0.01-0.99. |
