Using 4-bromophenyltristyrene as raw material, under the catalysis of CuI, TPE-I was synthesized (with a yield of 65%). The synthesis scheme is as follows: TPE-Br (1.0g, 2.44mmol), KI (3.64g, 21.96mmol),CuI (1.39 g, 7.34 mmol) and 100 mL of freshly distilled 1,3-dimethyl-2-imidazolinone (DMI) mixture were placed in a 250 mL three-necked flask.The reaction was stirred and heated vigorously at 200°C for 10 hours under the protection of nitrogen.After cooling to room temperature, brine was added.Then put the reaction vessel in an ice bath for several hours,The precipitated inorganic salt was removed by filtration, and the filtrate was extracted three times with dichloromethane.The organic layer was washed with brine and dried with MgSO4.After removing the solvent under reduced pressure, use silica gel column chromatography with petroleum ether as the eluent,A pale yellow solid powder was obtained.
