Embodiment 1
[0057] Embodiment 1: the synthesis of intermediate A1:
[0058] synthetic route:
[0059]
[0060]
[0061] Add 11.8g of 1,4-dibromobenzene (0.05mol) and 1.33g of Mg powder (0.055mol) and 60ml of tetrahydrofuran to a 250ml four-necked flask under nitrogen atmosphere, heat and reflux for 4 hours, the reaction is complete, and the format Reagent;
[0062] 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 Grignard salt into alcohol; after the reaction, extract with ether, dry and rotary evaporate, petroleum ether: dichloromethane mixed solvent (3:2) silica gel column purification to obtain a slightly yellow solid tertiary alcohol (yield 88%) ; using DEI-MS to identify the compound, formula C 22 h 19 BrO, detection value [M+1] + = 379.03, calculated value 378.06;
[0063] Take...

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...
