Embodiment 1

[0063] Taking Example 1 as an example, the synthetic route is as follows:

[0064]

[0065] Embodiment one:

[0066] Step 1) Preparation of Intermediate-1:

[0067] Throw in 40.0g (0.17mol) 4,6-dichloro-2-phenyl-5-aminopurine, 54.1g (0.17mol) 4,6-diphenyl-2-(4-aminophenyl)-1, 3,5-Triazine as the raw material, 1.926g (0.0017mol) tetrakistriphenylphosphorous palladium, 48.0g (0.5mol) sodium tert-butoxide, and 500.0g xylene, heated to 100-110°C, kept the temperature for 9hrs, Cool down to room temperature, add 300.0g of water, separate layers, desolventize the organic phase to obtain 98.3g of brown oily liquid, and obtain 18.6g (0.035mol) of Intermediate-1 by column chromatography;

[0068] Step 2) Preparation of Intermediate-2:

[0069] Add 18.6g (0.035mol) of intermediate-1 and 4.95g (0.035mol) of benzoyl chloride, 300.0g of DMF and 95.0g of silica gel loaded with ferric chloride (the content of aluminum chloride is 9%, about 0.053mol) , raised the temperature to 100-110...

Abstract

The invention discloses an OLED luminous composition and a preparation method thereof. The OLED luminous composition can be used for an OLED device, has excellent photoelectric properties and can be used as an organic material light-emitting layer and / or transmission layer. Compared with the prior art, the OLED luminous composition disclosed by the invention has the advantages that the OLED luminous composition has excellent photoelectric properties, and can be used for the OLED device to serve as the organic material light-emitting layer and / or transmission layer; the maximum current efficiency reaches 7.5 cd / A and the maximum brightness can reach 12749 cd / m<2>. The device disclosed by the invention has obvious advantages in aspects of brightness, efficiency and the like. As an electron and / or hole transmission material, the OLED luminous composition has the characteristics that drive voltage of the device can be remarkably reduced and the efficiency of the device is improved.

Description

technical field [0001] The invention relates to a novel OLED material and its application, belonging to the field of organic photoelectric materials. Background technique [0002] Organic electroluminescent (OLED: Organic Light Emission Diodes) device technology can be used to manufacture new display products and also can be used to make new lighting products, which is expected to replace the existing liquid crystal display and fluorescent lighting, and has a wide application prospect. [0003] The OLED light-emitting device is like a sandwich structure, including electrode material film layers, and organic functional materials sandwiched between different electrode film layers. Various functional materials are superimposed on each other according to the application to form an OLED light-emitting device. As a current device, when a voltage is applied to the electrodes at both ends of the OLED light-emitting device, and the positive and negative charges in the functional mate...
