AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT DEVICE USING THE SAME

摘要

An organic electroluminescent device may include an anode; an emission layer on the anode; and at least one layer between the anode and the emission layer, wherein the emission layer or the at least one layer includes an amine derivative represented by Formula 1. The organic electroluminescent device using the amine derivative represented by Formula 1 may have improved emission efficiency and emission lifetime.;

1. An amine derivative represented by Formula 1: wherein: X1 to X12 are each independently selected from hydrogen, deuterium, a halogen atom, a substituted or unsubstituted alkyl group having 1 to 15 carbon atoms, a substituted or unsubstituted aryl group having 6 to 36 carbon atoms for forming a ring, and a substituted or unsubstituted heteroaryl group having 1 to 36 carbon atoms for forming a ring, wherein a plurality of adjacent groups selected from X1 to X12 are optionally coupled to each other to form a condensed ring group; Ar1 and Ar2 are each independently selected from a substituted or unsubstituted aryl group having 6 to 36 carbon atoms for forming a ring, and a substituted or unsubstituted heteroaryl group having 1 to 36 carbon atoms for forming a ring, the aryl group excluding a pyrenyl group; and A is a halogen atom.
