Organic electroluminescent material and device thereof
-
Paragraph 0122-0125, (2020/07/15)
An organic electroluminescent material and a device thereof are disclosed. The organic electroluminescent material is a monoamine aromatic compound containing a dibenzo selenophen structure. The compound can be used as an organic layer material such as a hole transport material and an electron blocking material in an organic electroluminescent device. By using the compound, the characteristics ofheat resistance, driving voltage, luminous efficiency, service lifetime and the like of the OLED device can be effectively improved.

Provided are an organic EL device material capable of reducing the driving voltage of an organic EL device and increasing the lifetime of the device as compared with a conventional organic EL device material, specifically an aromatic amine derivative represented by N(Ara)(Arb)(Arc), and an organic EL device using the material. [Ara is represented by the formula (II). (In the formula (II): La represents a single bond or an arylene group; R1 to R4 each represent an alkyl group, an aryl group, or the like, and R3's or R4's, or R3 and R4 may be bonded to each other to form a ring; and o represents 0 to 3 and p represents 0 to 4.) Arb is represented by the formula (III). (in the formula (III), X represents NRa, O, or S, and Ra and R5 to R7 each represent an alkyl group, an aryl group, or the like, and R5's, R6's, or R7's adjacent to each other, or R5 and R6 may be bonded to each other to form a ring; n represents 2 to 4 when X represents NRa, and represents 0 to 4 when X represents O or S; and q represents 0 to 3, r and s each independently represent 0 to 4.) Arc represents an aryl group, or is represented by the formula (III).]
