Embodiment

[0085] Preparation

[0086] A method of synthesizing a material for an organic EL device and a method of manufacturing the organic EL device according to the present disclosure will be explained in more detail. However, the following examples are for illustration only, and the scope of the present disclosure is not limited thereto.

[0087] The synthetic method of compound 3

[0088] Compound 3 can be synthesized according to the following method. First, compound A was synthesized as an intermediate.

[0089]

[0090] Synthesis of Compound A

[0091] A solution of 8.00 g (30.9 mmol) of magnesium metal in 10 mL of dehydrated (eg, anhydrous) THF was added to a 500 mL three-necked flask, followed by stirring at about 0°C. A solution of 7.62 g (30.9 mmol) of 4-bromodibenzofuran in dehydrated THF was added dropwise, followed by stirring at room temperature for about 2 hours. A solution of 8.00 g (30.9 mmol) of 3-bromobenzophenone in 85 mL of dehydrated THF was added dropwis...

Abstract

Embodiments of the disclosure relate to a material (shown in the formula 1) for an organic electroluminescent device and a device using the material. Ar1 and Ar2 may be a substituted or unsubstituted aryl group having 6 to 30 carbon atoms or a substituted or unsubstituted heteroaryl group having 5 to 30 carbon atoms, Ar3 may be a substituted or unsubstituted aryl or heteroaryl group as above or an alkyl group having 1 to 6 carbon atoms, HAr may be a substituted or unsubstituted heteroaryl group having 5 to 30 carbon atoms, L may be selected from a direct linkage, a substituted or unsubstituted arylene group having 6 to 30 carbon atoms, and a substituted or unsubstituted heteroarylene group having 5 to 30 carbon atoms, and HAr and Ar3 may be different from each other.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Japanese Patent Application No. 2015-070934 filed in the Japan Patent Office on March 31, 2015, the entire contents of which are incorporated herein by reference. technical field [0003] One or more aspects of embodiments of the present disclosure relate to a material for an organic electroluminescent device, and an organic electroluminescent device including the material. Background technique [0004] Organic electroluminescent (EL) displays are currently being actively developed. Unlike liquid crystal displays and the like, organic EL displays are so-called self-luminous displays that operate by recombining holes and electrons from an anode and a cathode in a light-emitting layer to generate excitons. Light is emitted by the light-emitting organic compound in the light-emitting layer. [0005] An example organic EL device includes an anode, a hole transport layer o...
