Embodiment 1
[0213] Embodiment 1——Preparation of 3-trifluoromethoxy polytriphenylamine
[0214] 1. Preparation of Monomer 3-Trifluoromethoxytriphenylamine
[0215] In an open round bottom flask equipped with a magnetic stirrer and a thermometer, add 5 g of diphenylamine, 12.8 g of m-iodotrifluoromethoxybenzene, 1.5 mmol of palladium acetate, 6.2 g of potassium carbonate, and 250 mL of dimethyl sulfoxide (DMSO ) solvent, oscillating and mixing evenly and then warming up to 120°C and stirring the reaction under air, monitoring the reaction progress with TLC, stopping heating after the reaction is complete, quenching the reaction with saturated ammonium chloride solution after the mixture in the round bottom flask is cooled, and reacting After the mixture was extracted, dried, and concentrated under reduced pressure, the crude product obtained was separated and purified by column chromatography, and the eluent used was petroleum ether. The column chromatography eluate containing the product...
