<p>PURPOSE: An organic material and organic light emitting device using the same are provided to improve driving-voltage and luminous efficiency by offering organic material of which carrier transport property is improved. CONSTITUTION: An organic material comprises a compound in the chemical formula 1. In the chemical formula 1, A1, A2, A3, A4, B1, B2, B3 and B4 is respectively and independently selected from C1-C20 alkyl group, C1-C20 alkenyl group, amino group, C1-C20 ether group, C1-C20 carboxyl group, C1-C20 ester, nitro group, cyano group, C3-C30 aromatic group and halogen atoms. Among A1-A4 and B1-B4, at least one is substituted or unsubstituted aromatic group. Among the A1-A4 and B1-B4, at least one forms fused ring by connecting with neighbor substituent. M is divalent or trivalent metal. X is oxygen or sulfur. y is 2 or 3. An aromatic group included in at least one among A1-A4, locates on same plane with an aromatic group combined with A1-A4.</p> |
