摘要

PURPOSE: An organic electroluminescent compound is provided to have excellent luminous efficiency and lifetime comparison with existing dopant material, and to have moderate color coordination.;CONSTITUTION: An organic electroluminescent compound is in chemical formula 1. In chemical formula 1, L1 is an organic ligand, R1-R5 is respectively deuterium, halogen, substituted or non-substituted C3-30 cycloalkyl, substituted or non-substituted 5-7 membered heterocycloalkyl, cyano, nitro, BR21R22, PR23R24, P(=O)R25R26, R27R28R29Si-, substituted or non-substituted C6-30 ar C1-30 alkyl. R21-R26 is respectively substituted or non-substituted C1-30 alky, substituted or non-substituted C6-30 aryl, or substituted or non-substituted C3-30 heteroaryl. R27-R29 is respectively substituted or non-substituted C1-30 alkyl, substituted or non-substituted C6-30 aryl, or substituted or non-substituted C3-30 heteroaryl.;COPYRIGHT KIPO 2012
