ORGANIC LIGHT COMPOUND AND ORGANIC LIGHT DEVICE USING THE SAME

摘要

PURPOSE: An organic electroluminescent device is provided to improve luminous efficiency, brightness, color purity, thermal stability, and lifetime while having a low driving voltage by comprising a thiophene-based or amine-based compound. CONSTITUTION: An organic electroluminescent device comprises a first electrode, a second electrode, and at least one organic layer which is inserted in between the first and second electrodes. The organic layer comprises an organic light-emitting compound indicated in chemical formula F. In chemical formula F, X is N, S, Se, or Si; and each of E1 and E2 is selected from a C1-40 alkyl, C5-40 aryl, C3-40 heteroaryl, C5-40 aryloxy, C1-40 alkyloxy, C5-40 arylamino, C5-40 diarylamino, silane, C6-40 arylalkyl, C3-40 cycloalkyl, and C3-40 heterocycloalkyl group, or a group which can form a fused aliphatic ring, fused aromatic ring, fused heteroaliphatic ring, or fused heteroaromatic ring together with a neighboring group.
