-
Paragraph 0052-0054, (2019/02/04)
The invention discloses a red phosphorescent compound and an organic electroluminescence device employing the same. The structural formula of the red phosphorescent compound is as shown in the description, wherein formula represents formula, and R1, R2, R3 and R4 are independently selected from one of H and C1-C6 alkyl; in the formula (I), formula represents special alkyl diketone and derivativesthereof. The organic electroluminescence device comprises an anode, a hole injection layer, a hole transfer layer, a luminescent layer, an electron transfer layer, an electron injection layer and a cathode which are successively deposited. The organic electroluminescence device comprises the red phosphorescent compound as a doping agent. According to the red phosphorescent compound provided by theinvention, the organic electroluminescence device is high in efficiency, high in color purity and narrow in spectrum.

Paragraph 0030; 0031; 0032; 0033; 0034; 0035, (2017/02/09)
The invention discloses a high-purity 2-(3, 5-dimethylphenyl)-6-isobutyl quinoline synthesis method. The method comprises S1, preparing 6-isobutyl quinoline as a first intermediate, S2, preparing 2-(3, 5-dimethylphenyl)-6-isobutyl-1, 2-dihydro-quinoline as a second intermediate, S3, dissolving the 2-(3, 5-dimethylphenyl)-6-isobutyl-1, 2-dihydro-quinoline in a solvent, heating the solution to a temperature of 60 DEG C, adding an oxidizing agent into the solution for a reaction at a temperature of 0-100 DEG C, then cooling the product to a temperature of 0 DEG C, carrying out filtration when a lot of solids are separated and carrying out drying to obtain a finished product. The method can realize industrial production of high-purity 2-(3, 5-dimethylphenyl)-6-isobutyl quinoline, has a cost lower than that of the prior art and has a good market promotion prospect. The synthesis method is free of a purification process, reduces an organic waste yield in manufacture, saves resources and protects the environment.
