ORGANIC ELECTROLUMINESCENT COMPOUND CAPABLE OF EASILY CONDUCTING ENERGY MOVEMENT FROM HOST TO DOPANT, AND AN ORGANIC ELECTROLUMINESCENCE DEVICE COMPRISING THE SAME

摘要

PURPOSE: An organic electroluminescent compound is provided to have excellent electron transfer performance, hole transfer performance, and/or light-emitting performance(fluorescence or phosphorescence), and to able to provide an organic electroluminescence device with improved luminous efficiency, luminance, thermal stability, driving voltage, life time, etc.;CONSTITUTION: An organic electroluminescent compound is in chemical formula 1. In chemical formula 1, Ar1 and Ar2 is respectively hydrogen, deuterium, substituted or unsubstituted C1-40 alkyl, substituted or unsubstituted C2-40 alkenyl, substituted or unsubstituted C2-40 alkynyl, substituted or unsubstituted C3-40 cycloalkyl, substituted or unsubstituted C3-40 heterocycloalkyl, substituted or unsubstituted C6-40 arylalkyl, substituted or unsubstituted C1-40 alkyloxy, substituted or unsubstituted C5-40 aryloxy, substituted or unsubstituted C5-40 aryl, substituted or unsubstituted C5-40 heteroaryl, substituted or unsubstituted C6-40 arylamine, substituted or unsubstituted C6-40 heteroarylamine, substituted or unsubstituted silyl, or a group forming a fused ring by combined with a nearby group each other.;COPYRIGHT KIPO 2012
