Synthetic example 1
[0182] Synthesis Example 1 of the present invention exemplifies one of the compounds of the present invention, that is, the synthesis method of the compound formula (3-5) described in the examples to describe in detail.
[0183] First, under nitrogen, 1.5 g (4.6 mmole) of (4-bromo-phenyl)-diphenyl-amine was taken and dissolved in 20 ml of anhydrous THF solvent. Next, 3.2 ml of 1.6M n-BuLi (4.6 mmole×1.1) was added at −78° C., and the reaction solution was allowed to react for 3 hours. After that, 0.94 g (4.6 mmole) of 7-methoxy-5,5-dimethyl-2,3,4,4a,5,6-hexahydro-naphthalenone was dissolved in 10 ml of anhydrous THF solvent. And at a temperature of -78 degrees Celsius, it was added to the above reaction solution. Then, the reaction temperature was allowed to return to room temperature naturally, and the reaction was continued until the next day. Afterwards, water was added to the reaction solution to terminate the reaction. And add 30ml of ethyl acetate and acetic acid to c...
Synthetic example 2
[0191] The second synthesis example of the present invention exemplifies the synthesis method of one of the compounds of the present invention, that is, the compound formula (3-3) described in the examples to describe in detail.
[0192] First, under nitrogen, take 2 g (8 mmole) of 9-bromo-2,3,6,7-tetrohydro-1H,5H-pyrido[3,2,1-ij]quinoline and dissolve it in 20 ml of in anhydrous THF solvent. Next, 35.5 ml (8 mmole×1.1) of 1.6M n-BuLi was added at a temperature of −78° C., and the reaction solution was allowed to react for 3 hours. Afterwards, 1.64 grams (8 mmole) of 7-methoxy-5, 5-dimethyl-2, 3, 4, 4a, 5, 6-hexahydro-naphthalenone was dissolved in 10 ml of anhydrous THF solvent, and at -78 degrees Celsius Added to the above reaction solution at a temperature of Then, the reaction temperature was allowed to return to room temperature naturally, and the reaction was continued until the next day. Next, water was added to the reaction solution to terminate the reaction. And a...
Embodiment
[0201] The embodiment discloses a method for manufacturing an organic light emitting diode element with a three-layer structure. Please refer to Figure 4 Firstly, a glass substrate 100 of 100 mm×100 mm is provided. Afterwards, an indium tin oxide layer with a thickness of 150 nm is plated on the glass substrate 100 . Then, through lithography and etching process, the ITO layer is formed into several light-emitting area patterns of 10 mm×10 mm, which serve as an anode 102 . Then, at a vacuum of 10 -5 A vacuum evaporation step was performed in Pa, and a hole transport layer 112 with a thickness of 70 nm was plated on the surface of the anode 102 . The material of the hole transport layer 112 is NPB, and its evaporation rate is maintained at 0.2 nm / sec.
[0202] Next, the material of formula (1) and AlQ3 are respectively placed on two different evaporating dishes, and are vapor-deposited on the hole transport layer at the same time at the evaporation rates of 0.2nm / sec and 0...
