ORGANIC ELECTROLUMINESCENT ELEMENT AND COMPOUND HAVING CARBAZOLE RING STRUCTURE

[Problem] An organic compound of excellent characteristics is provided that exhibits excellent hole-injecting/transporting performance with electron blocking ability, and that has high stability in the thin-film state and high luminous efficiency, the organic compound being provided as material for an organic electroluminescent device having high efficiency and high durability. The invention also provides a high-efficient, high-durable organic electroluminescent device using the compound. [Means for Resolution] The compound is of the following general formula having a carbazole ring structure. The organic electroluminescent device includes a pair of electrodes, and one or more organic layers sandwiched between the pair of electrodes, and the compound is used as a constituent material of at least one organic layer.

AROMATIC AMINE DERIVATIVE AND ORGANIC ELECTROLUMINESCENT ELEMENT

Provided are a long-lifetime organic electroluminescence device which can be fabricated in an improved yield owing to suppressed crystallization of molecules, and an aromatic amine derivative that realizes the device, i.e. , a novel aromatic amine derivative having a specific structure. Specifically provided are an organic electroluminescence 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 an anode, and an aromatic amine derivative for at least one layer of the organic thin film layer, in particular, a hole transporting layer, the derivative having at least one such structure that a substituent in which two or more specific heterocycles are linked to each other, in particular, a substituent in which two or more specific heterocycles are linked through an aryl group is bonded to an amine through an aryl group.
