[0062] Synthesis of Intermediate 1-1;

[0063] Under nitrogen protection, in a four-necked flask equipped with mechanical stirring, add raw materials carbazole (30g, 180mmol, 1eq), 1-(4-bromophenyl)-4-chlorobiphenyl (61.4g, 180mmol, 1eq), three (dibenzylideneacetone) dipalladium (5.0g, 5.4mmol, 3%eq), tri-tert-butylphosphine tetrafluoroborate (3.1g, 10.8mmol, 6 %eq), sodium tert-butoxide (26g, 270mmol, 1.5eq), and 300mL toluene were reacted at 80°C for 24h. After cooling down to room temperature, 250 mL of aqueous solution was added directly, the aqueous phase was extracted three times with 200 mL of dichloromethane, and the combined organic phases were concentrated to obtain a crude product. The crude product was boiled and washed in petroleum ether, and filtered to obtain 27g of white powder.

Abstract

The invention discloses a general formula compound with the following structure, wherein R1 is selected from C6-C30 aryl or fused ring aryl, C3-C30 heterocyclic aryl or fused ring heteroaryl; R2 and R3 are independently selected from hydrogen, C1-C12 alkyl, C1-C8 alkoxy, C6-C30 aryl or fused ring aryl, C3-C30 heterocyclic aryl or fused ring heteroaryl; M and n are each independently selected fromintegers of 1 to 4; L is selected from single bonds, or C1-C12 alkyl, C1-C8 alkoxy, C5-C30 arylene, C3-C30 heterocyclic arylene; Ar1 and Ar2 are independently selected from C6-C30 aryl or fused ring aryl respectively; Ar3 and Ar4 are independently selected from C6-C30 aryl or fused ring aryl, C3-C30 heterocyclic aryl or fused ring heteroaryl respectively. The invention also protects the organic electroluminescent device adopting the general formula compound. When the compound is used as a hole transport material in an OLED light emitting layer, the compound exhibits excellent device performance and stability.

Description

technical field [0001] The invention relates to the field of organic electroluminescent materials, in particular to a novel general formula compound and an organic electroluminescent device using the general formula compound. Background technique [0002] Organic light-emitting diodes (Organic Light-Emitting Diodes, OLEDs) are also known as organic electro-laser displays and organic light-emitting semiconductors. It was discovered in the laboratory by Chinese-American professor Ching W.Tang in 1979. OLED display technology has the advantages of self-illumination, wide viewing angle, high contrast, low power consumption, and fast response speed. However, as a high-end display, the price will be more expensive than LCD TVs. Among them, OLED itself has the inherent characteristics of using organic thin film and applying voltage to the device composed of it to emit light. Therefore, the development of suitable organic thin film materials has always been the research focus of t...
