Embodiment 1

[0051] Synthesis of shared intermediates:

[0052]

[0053] Synthesis of compound 03: To a 2L single-necked bottle, compound 01 (53.17g, 0.57mol, 1.0eq), compound 02 (200g, 0.57mol, 1.0eq), NaHCO 3 (94.9g, 1.14mol, 2.0eq), and isopropanol (1000ml) were put into the flask, heated to about 80 degrees in an oil bath, kept stirring and refluxed for 7 hours, and the reaction of raw materials was monitored by sampling TLC. Cool down, add deionized water dropwise, stir for about 4 hours, and filter with suction. The solid was slurried with ethanol, filtered and dried with suction. 157 g of white solid compound 03 was obtained with a yield of 79.6%. Mass spectrum: 349.03 (M+H)

[0054] Synthesis of Compound 04: Add Compound 03 (60g, 171.81mmol, 1.0eq), bis-pina boronate (56.72g, 223.35mmol, 1.3eq), Pd(dppf)Cl to a 1L single-necked bottle in sequence 2 (1.26g, 1.72mmol, 0.01eq), CH 3 COOK (33.72g, 343.62mmol, 2.0eq), 600ml of dioxane, N2 replacement 3 times under stirring, heat...

Description

technical field [0001] The invention relates to the technical field of organic electroluminescence, in particular to a dibenzoheterocyclic organic compound of imidazo[1,2-a]pyridine and its application in organic electroluminescence devices. Background technique [0002] At present, as a new generation of display technology, organic electroluminescent devices (OLEDs) have received more and more attention in both display and lighting technologies, and have a wide application prospect. However, compared with market application requirements, the luminous efficiency, driving voltage, service life and other performances of OLED devices need to be continuously strengthened and improved. [0003] Generally speaking, the basic structure of an OLED device is a thin film of organic functional materials with various functions mixed between metal electrodes, like a sandwich structure. Driven by current, holes and electrons are injected from the cathode and anode, holes and electrons res...
