Organic compound for organic electroluminescent device

Abstract

The present invention discloses a novel organic compound is represented by the following formula(A), the organic EL device employing the compound as blue emitting layer can lower driving voltage, prolong half-lifetime and increase the efficiency. Wherein m represent an integer of 0 to 8, n represent an integer of 0 to 10, p represent an integer of 0 to 7, HAr represent a hydrogen, a halide, a cyanine group, a substituted or unsusbstituted heteroaryl group system having 5 to 6 aromatic ring atoms, R1 to R4 are identical or different. R1 to R4 are independently selected from the group consisting of a hydrogen atom, alkyl group having 1 to 30 carbon atoms, a substituted or unsubstituted aryl group having 6 to 30 carbon atoms, a substituted or unsubstituted aralkyl group having 6 to 30 carbon atoms.
