Embodiment 1

[1022] (manufacture of organic EL elements)

[1023] A glass substrate with an ITO transparent electrode of 25 mm x 75 mm x 1.1 mm (manufactured by Geomatec) was subjected to ultrasonic cleaning in isopropanol for 5 minutes, and then to UV (Ultraviolet) ozone cleaning for 30 minutes.

[1024] The glass substrate with the transparent electrode thus cleaned is assembled on the substrate holder of the vacuum evaporation device, firstly, on the surface of the glass substrate on the side where the transparent electrode line is formed, the compound A is vapor-deposited with a thickness of 30 nm to cover the transparent electrode, A hole transport layer was obtained.

[1025] Compound No. 11 as a host for phosphorescence and Ir(Ph-ppy) as a dopant for phosphorescence were co-deposited in a thickness of 30 nm on this hole transport layer. 3 , to obtain a phosphorescent layer. Ir(Ph-ppy) 3 The concentration is 5% by mass.

[1026] Next, compound B with a thickness of 10 nm, compoun...

Embodiment 2～34

[1032] An organic EL device was produced and evaluated in the same manner as in Example 1, except that the host material described in Table 1 was used instead of host compound No. 11 in Example 1. Table 1 shows the evaluation results of luminous performance.

Embodiment 35

[1052] (manufacture of organic EL elements)

[1053]A glass substrate with a transparent electrode washed in the same manner as above was mounted on a substrate holder of a vacuum deposition device, and first, the surface of the glass substrate on which the transparent electrode line was formed was deposited with a compound A to a thickness of 30 nm to cover it. Transparent electrodes, resulting in a hole transport layer.

[1054] Compound No. 108 as a host for phosphorescence and Ir(Ph-ppy) as a dopant for phosphorescence were co-deposited in a thickness of 30 nm on this hole transport layer. 3 , to obtain a phosphorescent layer. Ir(Ph-ppy) 3 The concentration is 10% by mass.

[1055] Next, Compound No. 92 with a thickness of 10 nm, Compound C with a thickness of 20 nm, LiF with a thickness of 1 nm, and metal Al with a thickness of 80 nm were sequentially laminated on the phosphorescent layer to obtain a cathode. Moreover, for LiF as an electron-injecting electrode, with ...

Abstract

Disclosed is a polycyclic compound having a p-conjugated heteroacene skeleton crosslinked via a carbon atom, a nitrogen atom, an oxygen atom or a sulfur atom. Also disclosed is a halogen compound which can be used for the synthesis of the polycyclic compound. Further disclosed is an organic electroluminescence element which comprises a cathode, an anode, and at least one organic thin film layer containing a light-emitting layer and arranged between the cathode and the anode, wherein at least one layer in the organic thin film layer comprises a material for the organic electroluminescence element. The organic electroluminescence element has high luminous efficiency and has long service-life. The polycyclic compound can be used for the production of the organic electroluminescence element. The halogen compound is an intermediate for the polycyclic compound.

Description

technical field [0001] The present invention relates to a halogen compound, a polycyclic compound and an organic electroluminescent device using the same, and in particular to an organic electroluminescent device with high luminous efficiency and long life, a polycyclic compound for realizing the same, and a halogen as an intermediate thereof compound. Background technique [0002] Organic electroluminescent elements (hereinafter sometimes referred to as EL for short) are self-luminous elements that use the principle of recombination energy of holes injected from the anode and electrons injected from the cathode to make fluorescent substances emit light by applying an electric field. . Since the report of a low-voltage-driven laminated organic EL element, research on an organic EL element using an organic material as a constituent material has become increasingly active. In this laminated device, tris(8-quinolinolato)aluminum is used for the light emitting layer, and a tri...
