Embodiment 1

[0036] Embodiment 1. two (oxypropyl diacrylate aniline phenyl vinyl) biphenyl and photocrosslinking cured product are as shown in Figure 2:

[0037] (1) Synthesis of bis(oxypropyl diacrylate aniline phenylvinyl)biphenyl

[0038] Dissolve 18 parts by mass of bis-p-methoxyanilino-p-benzene in 70-100 parts by mass of dry dimethylformamide DMF solvent, and add 8.43-9.97 parts by mass of phosphorus oxychloride POCl dropwise 3 600 parts by mass of dry dimethylformamide solution. Stir at room temperature for 1-2 hr. The reaction liquid was slowly added to 2000 parts of mass ice water, the precipitate was filtered, washed with water, dried, and passed through a silica gel column with a developing agent with a volume ratio of ethyl acetate and benzene of 2:8 to obtain the product (a)—dimethoxyaniline p- 13~15 parts of quality of benzaldehyde.

[0039] Dissolve 25 parts by mass of 4,4'-dichloromethylbiphenyl and 25 to 30 parts by mass of triphenylphosphine in 160 to 200 parts by mass...

Embodiment 2

[0049] Embodiment 2. two (oxyisobutyl diacrylate aniline phenyl vinyl) biphenyl and its photocrosslinking cured product

[0050] Such as image 3 Shown:

[0051] (1) Synthesis of bis(oxyisobutyl diacrylate aniline phenylvinyl)biphenyl

[0052] Add K 2 CO 3 (20.7-27.6 parts by mass). After stirring for 12 hours at 50°C, the organic phase was extracted with 500 parts by mass of ethyl acetate and 3000 parts by mass of water, dried over anhydrous magnesium sulfate, filtered, and evaporated to remove the solvent to obtain the product (g)—bis(di-p-hydroxyisobutoxy 13-16 parts of mass of aniline phenyl vinyl) biphenyl.

[0053] Add DCC (21.5 to 22.6 parts mass). Stir at room temperature for 9-11 hours, and then add 2000-3000 parts by mass of water. The organic phase was extracted with ethyl acetate. After evaporating the solvent, use toluene-ethyl acetate (8:2) to pass through a silica gel column to obtain the product (h)——17.5-20 parts by mass of bis(diacrylateoxyisobutylani...

Embodiment 3

[0060] Embodiment 3. bis (oxypentyl dimethacrylate aniline phenyl vinyl) biphenyl and photocrosslinking cured product thereof

Abstract

The invention relates to a diphenylamine-styrene biphenyl compound containing a photocrosslinking group, and the application in preparing a blue-light organic electroluminescent material and in organic electroluminescence, and belongs to the technical field of organic semiconductor light-emitting material. A substance with UV curing activity is formed by connecting olefinic acid ester with benzene ring of diphenylamine-styrene biphenyl, which is the blue-light organic electroluminescent material, and the substance is mixed with a small amount of UV-curable initiator to form a film by spin coating and is crosslinked under the action of UV rays to form an organic electroluminescent layer insoluble in a solvent. The product can prevent interlayer mixing while multilayer spin coating, and the side group has less influence on the light emission performance. The method is a better method for preparing the organic electroluminescent layer.

Description

technical field [0001] The invention belongs to the technical field of organic flat panel displays, and in particular relates to the preparation and application of a photo-crosslinkable organic electroluminescent material containing enolate side groups. Background technique [0002] Organic Light Emitting Display, (Organic Light Emitting Display referred to as OLED), which belongs to the newly emerging category on mobile phone screens, MP3 and MP4 screens, is known as "dream display". OLED display technology is different from traditional LCD display methods. It does not require a backlight, and uses very thin organic material coatings and glass substrates. When an electric current passes through, these organic materials will emit light. Therefore, OLED screens can be made lighter and thinner, have a larger viewing angle, and can significantly save power. [0003] The structure of an OLED display typically has several layers of organic material between the metal cathode and ...
