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 ...
