NOVEL ORGANIC ELECTROLUMINESCENT COMPOUNDS AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

PURPOSE: An organic electroluminescent compound is provided to ensure good luminous efficiency and excellent lifetime properties of materials, to improve driving durability of devices and to obtain an organic light emitting diode device with improve power consumption. CONSTITUTION: An organic electroluminescent compound represented by chemical formula 1, wherein ring A and ring B represent a 6-membered aromatic ring or a 6-membered hetero aromatic ring; p and r represent an integer from 0 to 2, and q and s represent an integer from 2 to 4, with the proviso that p+r>=l, p+q<4 and r+s<=4; Li and L2 independently represent a chemical bond, (C6-C30)arylene with or without substituent(s), (C3-C30)heteroarylene with or without substituent(s), 5- to 7-membered heterocycloalkylene with or without substituent(s),; Ari and Ar2 independently represent hydrogen, halogen, (Cl-C30)alkyl with or without subst ituent (s), (C6-C30)aryl with or without substituent (s), substituted or unsubstituted (C6-C30)aryl fused with one or more (C3- C30)cycloalkyl with or without subst ituent (s); Rn through R2o independently represent (Cl-C30)alkyl with or without substituent (s), (C6-C30)aryl with or without subst ituent(s) or (C3- C30)heteroaryl with or without subst ituent(s) or each of them may be linked to an adjacent substituent via (C3-C30)alkylene or (C3-C30)alkenylene with or without a fused ring to form an alicylic ring or a mono- or polycyclic aromatic ring.
