Embodiment 1

[0109] Embodiment 1: the preparation of compound 1

[0110]

[0111] Dissolve 3.21g (10mmol) of bis([1,1'-biphenyl]-4-yl)amine and 4.45g (10mmol) of 2'-bromospiro[benzo[de]anthracene- 7,9'-fluorene], 2.88 g (30 mmol) of sodium tert-butoxide, 161 mg (0.4 mmol) of tri-tert-butylphosphine (50 wt % in toluene), 115 mg (0.2 mmol) of bis(dibenzyl Proxyl acetone) palladium (0), followed by stirring and reflux for 3 hours. After finishing the reaction, cool at room temperature, and add 50ml of ethyl acetate and 50ml of H 2 O to extract the organic layer. Using MgSO 4 After treating the organic layer, it was filtered, dried, and columnized with n-hexane / dimethylammonium chloride to obtain Compound 1 in a yield of 85% (5.83 g).

Embodiment 2

[0112] Embodiment 2: the preparation of compound 2

[0113]Instead of using 4.58 g (10 mmol) of N-phenylspiro[benzo[de]anthracene-7,9'-fluorene]-2'-amine and 2.13 g (10 mmol) of 1-bromo-4-(tert-butyl Base) benzene to replace bis([1,1'-biphenyl]-4-yl)amine and 2'-bromospiro[benzo[de]anthracene-7,9'-fluorene], in order to implement Compound 2 was prepared in the same manner as Example 1.

Embodiment 3

[0114] Embodiment 3: the preparation of compound 6

[0115] Using 3.35 g (10 mmol) of N-([1,1'-biphenyl]-4-yl)dibenzo[b,d]furan-4-amine and 4.77 g (10 mmol) of 2'-bromospiro [Benzo[de]anthracene-7,9'-fluorene] instead of bis([1,1'-biphenyl]-4-yl)amine and 2'-bromospiro[benzo[de]anthracene-7 , 9'-fluorene], Compound 6 was prepared in the same manner as in Example 1.

Abstract

The invention relates to an organic material containing spiro (benzo[de]anthracene-7.9'-fluorene) and an organic electroluminescent device utilizing the same, specifically to a new spiro-typed organic material used to an organic electroluminescent device and an organic electroluminescent device having excellent features of low electric power and high efficiency using the organic material.

Description

technical field [0001] The present invention relates to a new spirocyclic organic compound and an organic electroluminescent device using it. Background technique [0002] Organic semiconductors are being developed for application to various types of various electronic devices. Compared with other flat-panel display elements such as existing liquid crystal display (LCD), plasma display panel (PDP) and field emission display (FED), organic electroluminescent devices have many advantages in the preparation process due to their simple structure. High brightness, excellent viewing angle characteristics, fast response speed, and low driving voltage are being actively developed as light sources for flat panel displays such as wall-mounted TVs (TVs) or displays, lighting, and advertising boards. [0003] In organic electroluminescent devices, generally, when a DC voltage is applied, holes injected from the anode and electrons injected from the cathode recombine to form excitons as...
