PYRIDOIMIDAZOLE BASED DERIVATIVE CAPABLE OF ENHANCING LUMINOUS EFFICIENCY, LUMINESCENT BRIGHTNESS, AND CHROMATIC PURITY AND LUMINESCENCE LIFETIME AND AN ORGANIC LIGHT DEVICE USING THE SAME

摘要

PURPOSE: A pyridoimidazole based derivative and an organic light device using the same are provided to enhance luminescence lifetime, luminous efficiency, luminescent brightness, and chromatic purity.;CONSTITUTION: An organic light device comprises a first electrode, a second electrode, a first electrode, one or more organic layers between the first and second electrodes. The organic layer includes the organic light compound of the following chemical formula F. Here, X indicates C or N, R1, R2, R3 and R4 are respectively selected from H, D, C1-40 alkyl group, C5-40 aryl group, C5-40 heteroaryl group, C5-40 aryloxy group, C1-40 alkyloxy group, C5-40 arylamino group, C5-40 diarylamino, C6-40 arylalkyl group, C3-40 cycloalkyl group and C3-40 heterocycloalkyl group, or a group which forms neighboring group, fused aliphatic ring, condensed aromatic ring, condensation heteroaliphatic loop or condensation hetero aromatic ring.;COPYRIGHT KIPO 2013
