- AROMATIC AMINE DERIVATIVES AND ORGANIC ELECTROLUMINESCENT ELEMENTS USING SAME
-
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).]

- AROMATIC AMINE DERIVATIVE, AND ORGANIC ELECTROLUMINESCENT ELEMENT
-
Provided are: an aromatic amine derivative including a substituent A and a substituent B each represented by the formula (1) or (2) and having an arylene group bound to a carbazole structure, in which the substituent A and the substituent B include groups different from each other in the position at which the arylene group is bonded to the carbazole structure, and the substituent A and the substituent B are bonded to the same nitrogen atom or different nitrogen atoms in the molecule; an organic electroluminescent device including an organic thin-film layer formed of one or more layers including at least a light emitting layer, the organic thin-film layer being interposed between a cathode and a anode, in which at least one layer of the organic thin-film layer contains the aromatic amine derivative, and the molecules are rarely crystallized, the yield upon production of the organic electroluminescent device is improved, the driving voltage for the organic electroluminescent device is low, and the lifetime of the organic electroluminescent device is long; and an aromatic amine derivative which can realize the organic electroluminescent device. (In the formulae, each substituent is as described in claim 1.)
