NOVEL ORGANIC ELECTROLUMINESCENCE COMPOUNDS AND ORGANIC ELECTROLUMINESCENCE DEVICE USING THE SAME

摘要

PURPOSE: An organic electroluminescence compound is provided to manufacture an organic electroluminescence device with improved power efficiency and power consumption by having excellent light-emitting efficiency and material lifetime. CONSTITUTION: An organic electroluminescence compound is indicated in chemical formula 1. In chemical formula 1, each of L1 and L2 is a single bond, a substituted or unsubstituted (C2-30)heteroarylene, a substituted or unsubstituted (C6-30)arylene, or a substituted or unsubstituted (C3-30)cycloalkylene, each of X1 and X2 is CH or N, each of Y1 and Y2 is -O-, -S-, -CR5R6- or -NR7-, Y2 and Y3 cannot exist at the same time, and each of Ar is hydrogen, deuterium, halogen, a substituted or unsubstituted (C1-30)alkyl, a substituted or unsubstituted(C6-30)aryl, a substituted or unsubstituted (C2-30)heteroaryl, or N-carbazolyl.
