摘要

The present invention discloses an novel organic material is represented by the following formula (A) and organic EL device using the organic material as hole blocking layer (HBL), electron transport layer (ETL) or phosphorescent host can efficiently lower driving voltage, lower power consumption and increase the efficiency.;;The same definition as described in the present invention.

主权项

1. A organic material with a general formula (A) as following:Wherein m represent 0 to 2, and when m represent 1 or 2, L represent a single bond, a substituted or unsubstituted arylene group having 6 to 40 ring carbon atoms, or a substituted or unsubstituted heterarylene group having 3 to 40 ring carbon atoms. When m represent 0, L represent a substituted or unsubstituted heterarylene group having 3 to 40 ring carbon atoms. X represent O, S, NR5. Y1 to Y4 each independently represent nitrogen atom or CR6. R5 and R6 independently represent a hydrogen atom, a substituent, or a bond to L. p represent an integer of 0 to 7, q represent an integer of 0 to 10. R1 to R4 independently selected from the group consisting of a hydrogen atom, a halide, alkyl group having 1 to 20 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, a substituted or unsubstituted heteroaryl group having 3 to 30 carbon atoms.
