[0276] [Example 1] Red organic electroluminescence element (luminescence auxiliary layer)

[0277] An organic electroluminescent element is manufactured using the compound of the present invention as a material for an emission-assisting layer according to a conventional method. First, 4,4',4"-tris[2-naphthyl(phenyl)amino]triphenylamine (hereinafter referred to as 2-TNATA ) to a thickness of 60nm to form a hole injection layer. Then, on the hole injection layer, vacuum deposit N, N'-bis(1-naphthyl)-N,N'-bisphenyl-(1,1 '-biphenyl)-4,4'-diamine (hereinafter referred to as NPB) to a thickness of 60nm to form a hole transport layer. Subsequently, on the hole transport layer, the compound P-1 of the present invention is vacuum-deposited to After forming the luminescence auxiliary layer with a thickness of 20nm, 4,4'-N,N'-dicarbazole-biphenyl (hereinafter referred to as CBP) was used as the host material on the luminescence auxiliary layer, and bis-(1-phenyl Isoquinolyl) iridium (I...

Description

technical field [0001] The present invention relates to a compound used for organic electronic components, an organic electronic component using the compound, and an electronic device thereof. Background technique [0002] Generally, the organic light emitting phenomenon refers to a phenomenon in which electrical energy is converted into light energy by using an organic material. An organic electronic element utilizing the organic light-emitting phenomenon generally has a structure including an anode, a cathode, and an organic material layer interposed therebetween. In many cases, the organic material layer can be formed as a multilayer structure composed of different materials in order to improve the efficiency and stability of organic electronic components, for example, it can be composed of hole injection layer, hole transport layer, light emitting layer, layer and electron injection layer. [0003] In organic electronic elements, materials used for organic material lay...
