ORGANIC LIGHT COMPOUND AND ORGANIC LIGHT DEVICE USING THE SAME

摘要

PURPOSE: A purine based derivative capable of being used as electron transporting material and an organic light device including the same are provided to express excellent luminous efficiency, luminescent brightness, chromatic purity and luminescence lifetime. 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, A1, A2 , A3 and A4 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.
