Embodiment 1

[0045] Embodiment 1: 1,3,5-three [(N'-butyl)-1 ', the synthesis of 8'-naphthalimide-4'-base] benzene

[0046] use as figure 1 Shown synthetic route prepares, specifically comprises the following steps:

[0047] (1), 1,3, the synthesis of 5-benzenetriboronic acid-tributanol ester

[0048] After passing nitrogen gas in a 250ml three-necked flask for 30min, add bisglutaryl boron (33mmol), appropriate amount of PdCl 2 With dppf, 90mmol potassium acetate, 1,3,5-bromobenzene (10mmol), and 120ml dimethyl sulfoxide (DMSO), heat and stir at 70°C until the raw material 1,3,5-bromobenzene disappears, and the reaction is terminated. After the reaction liquid was cooled to room temperature, it was filtered, and dimethyl sulfoxide (DMSO) was distilled from the filtrate under reduced pressure. The evaporated matter was washed with water with the filter cake, extracted with benzene, and the extract was dried with anhydrous magnesium sulfate. The solvent was distilled off by rotary distill...
