Embodiment 1

[0046] The synthesis of embodiment 1 compound 2:

[0047]

[0048] synthetic route:

[0049]

[0050] In a 250ml four-necked flask, under nitrogen atmosphere, add 16.2g 4-(4-bromo-phenyl) dibenzofuran (0.05mol) and 1.44g Mg powder (0.06mol), 60ml tetrahydrofuran, heat to reflux for 4 hour, the reaction is complete, and the format reagent is generated;

[0051] Dissolve 11.1g of 10,10-dimethylanthrone (0.05mol) in 50ml of tetrahydrofuran, add the above-mentioned Grignard reagent dropwise, react at 60°C for 24 hours, a large amount of white precipitate is formed, and finally add saturated NHCl 4 Convert the Grignard salt into alcohol; after the reaction, extract with ether, dry and rotary evaporate, and purify on a silica gel column with a mixed solvent of petroleum ether: dichloromethane (3:2) to obtain a slightly yellow solid tertiary alcohol (85% yield) ; using DEI-MS to identify the compound, formula C 34 h 26 o 2 , detection value [M+1] + = 466.93, calculated va...

Embodiment 2

[0054] The synthesis of embodiment 2 compound 4:

[0055]

[0056] synthetic route:

[0057]

[0058] Prepared according to the synthetic method of compound 1 in Example 1, the difference is that 4-(4-bromo-phenyl) dibenzofuran is replaced by 6-(4-bromo-phenyl)naphthobenzofuran, and biphenyl instead of benzene;

[0059] Using DEI-MS to identify the compound, formula C 50 h 36 O, detection value [M+1] + =653.13, calculated value 652.28.

Embodiment 3

[0060] The synthesis of embodiment 3 compound 28:

[0061]

[0062] synthetic route:

[0063]

[0064] Prepared according to the synthetic method of compound 1 in Example 1, the difference is that 1-(4-bromo-phenyl)-9,9-dimethylfluorene is used instead of 4-(4-bromo-phenyl)dibenzofuran , replace benzene with biphenyl;

[0065] Using DEI-MS to identify the compound, formula C 49 h 40 , detection value [M+1] + =629.15, calculated value 628.31.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric materials, in particular to a compound material containing a dimethyl anthracene structure as a central skeleton and its application in the field of OLEDs. Background technique [0002] Organic electroluminescent (OLED: Organic Light Emission Diodes) device technology can be used to manufacture new display products and also can be used to make new lighting products, which is expected to replace the existing liquid crystal display and fluorescent lighting, and has a wide application prospect. [0003] The OLED light-emitting device is like a sandwich structure, including electrode material film layers, and organic functional materials sandwiched between different electrode film layers. Various functional materials are superimposed on each other according to the application to form an OLED light-emitting device. As a current device, when a voltage is applied to the electrodes at both e...
