Thermally induced delayed fluorescence material based on anthrone receptor and preparation method thereof

[0025] This example provides a preparation method of anthracene-9-yl (4-(3,6-di-tert-butyl-9h-carbazol-9-yl)phenyl) ketone ketone material, the specific steps are:

[0026] (1) Synthesis of anthracen-9-yl(4-iodophenyl)methanone.

[0027] Take a 500mL three-necked reaction bottle in the oven, add a magnetic rotor, assemble the reaction system while it is hot, and vacuumize the system, add 4-iodobenzoyl chloride (7.98g, 30mmol) and anthracene (6.41g, 35mmol) under nitrogen atmosphere , and add 250ml of dried CH2Cl2 solution, seal the system, change the nitrogen gas 3 times continuously, add AlCl3 (5.20g, 38mmol) to the reaction solution under the condition of nitrogen gas, and keep the reaction in a nitrogen environment. , The reflux temperature was 45°C and stirred for 4h. The reaction solution was cooled to room temperature, and the solvent was removed by rotary evaporation. The obtained product was ultrasonically dissolved with a very small amount of CH2Cl2 solution, and purifi
