Embodiment approach 1

[0204] In this embodiment mode, the anthracene derivative of the present invention will be described.

[0205] The anthracene derivative of the present invention is an anthracene derivative represented by the general formula (1).

[0206]

[0207] (where, Ar 1 and Ar 2 Respectively represent the aryl group with 6 to 25 carbon atoms, Ar 3 represents an arylene group having 6 to 25 carbon atoms, and A represents any one of substituents represented by general formulas (1-1) to (1-3). In general formula (1-1)~(1-3), Ar 11 ~ Ar 13 Represents an aryl group with 6 to 25 carbon atoms, α represents an arylene group with 6 to 25 carbon atoms, Ar 21 Represents an aryl group with 6 to 25 carbon atoms, R 31 Represents any one of a hydrogen atom, an alkyl group with 1 to 4 carbon atoms, an aryl group with 6 to 25 carbon atoms, a halogen atom or a halogenated alkyl group with 1 to 4 carbon atoms, R 32 Represents any one of an alkyl group with 1 to 4 carbon atoms, an aryl group with...

Embodiment approach 2

[0362] Below, use Figure 1A One embodiment of a light-emitting device using the anthracene derivative of the present invention will be described.

[0363] The light-emitting element of the present invention has a plurality of layers between a pair of electrodes. The plurality of layers is formed by combining a layer formed of a substance having a high carrier injection property and a layer formed of a substance having a high carrier transport property to form a light emitting region at a position away from the electrode, that is, In order to carry out the recombination of carriers at a site far away from the electrodes.

[0364] In this embodiment, the light emitting element is composed of a first electrode 102 , a second electrode 104 , and an EL layer 103 provided between the first electrode 102 and the second electrode 104 . In addition, in the following description, it is assumed that the first electrode 102 is used as an anode and the second electrode 104 is used as a ...

Embodiment approach 3

[0401] In this embodiment mode, a light emitting element having a structure different from that shown in Embodiment Mode 2 will be described.

[0402] Light emission from the anthracene derivative of the present invention can be obtained by dispersing the anthracene derivative of the present invention in another substance to form the light-emitting layer 113 described in Embodiment Mode 2. Since the anthracene derivative of the present invention exhibits blue to yellow-green light emission, a light-emitting device that exhibits blue to yellow-green light emission can be obtained.

[0403] Here, as the substance for dispersing the anthracene derivative of the present invention, various materials can be used, and in addition to the substances having high hole-transporting properties and the substances having high electron-transporting properties described in Embodiment Mode 2, 4 listed above can also be used. , 4'-bis(N-carbazolyl)biphenyl (abbreviation: CBP), 2,2',2"-(1,3,5-ben...

Abstract

The invention is to provide a novel anthracene deruivative. Further, the invention is to provide a luminous element with a high luminous efficiency. Further, the invention is to provide a luminous device and an electronic equipment with a long service life by using the luminous element. The invention provides an anthracene deruivative represented by the formula (1). Further, because the anthracene deruivative represented by the formula (1) has a high luminous efficiency, a luminous element with a high luminous efficiency can be obtained by using the anthracene deruivative into the luminous element. In addition, a luminous element with a long service life can be obtained by using the anthracene deruivative represented by the formula (1) into the luminous element.

Description

technical field [0001] The present invention relates to anthracene derivatives, organic compounds, and light-emitting devices and electronic devices using anthracene derivatives. Background technique [0002] Compared with inorganic compounds, organic compounds can have a variety of structures, and it is possible to synthesize materials with various functions through appropriate molecular design. Due to these advantages, optoelectronics and electronics using functional organic materials have attracted attention in recent years. [0003] For example, examples of electronic devices using organic compounds as functional organic materials include solar cells, light-emitting elements, organic transistors, and the like. These are devices utilizing the electrical and optical properties of organic compounds, and particularly light-emitting elements have been remarkably developed. [0004] The light-emitting mechanism of the light-emitting element is as follows: By applying a volta...
