Embodiment Construction
[0015] The present invention will be described in detail below in conjunction with accompanying drawing:
[0016] (1) Synthesis of dispersing aids
[0017] Argon was introduced into the 100ml polymerization bottle, and 2-amino-4,6-diiodopyrimidine (0.4160mmol, 144.31 mg), 2,7-bis(4,4,5,5-tetramethyl -1,3,2-dioxaborolan-2-yl)-9,9-dioctylfluorene (0.4160 mmol, 267.31 mg), cesium carbonate Cs 2 CO 3 (2.08 mmol , 676.0 mg), add 20.8 mL DME and 10.4 ml deionized water, pass argon gas under electromagnetic stirring for 15 min, add zero-valent palladium catalyst Pd (PPh 3 ) 4 (0.0208 mmol, 23.9 mg), under the protection of argon, the reaction system was refluxed at 58-60 ° C for 48 h, the reactant was cooled to room temperature, the product was washed with methanol and distilled water successively, recrystallized from chloroform / methanol three times, and then After washing with methanol and vacuum drying at 50°C for 48 h, 138 mg of light yellow powder was obtained with a yield ...
