Examples
Embodiment 1
[0034] Dissolve phenanthrene-9,10-dione (1.25g, 6mmol) in 20ml of 98% sulfuric acid solution, and add NBS (2.668g, 15mmol) to the above solution, and stir at room temperature for 4h. The mixture was poured on crushed ice to give an orange crude product, which was washed with cold water. The washed crude product was recrystallized in DMSO to obtain the product 2,7-dibromophenanthrene-9,10-dione (1.965 g, yield 72%). Its chemical reaction equation is:
[0035]
Embodiment 2
[0037] 2,7-Dibromophenanthrene-9,10-dione (0.73 g, 2 mmol) and diaminobenzene (0.216 g, 2 mmol) were dissolved in 10 ml of ethanol. The catalyst PTSA is added to the solution. The mixture was refluxed for 5 hours. The obtained yellow suspension was filtered and washed with ethanol to obtain the product 2,7-dibromodibenzophenazine (0.82g, yield 82%), and its chemical reaction equation was:
[0038]
Embodiment 3
[0040] Add 3,4-ethylenedioxythiophene (5mL, 27.86mmol), glacial acetic acid (50ml) and concentrated sulfuric acid (50ml) into a 250ml single-necked bottle at 0-5°C, and stir in the dark. Then add (12.3g, 180mmol) N-bromosuccinimide (NBS) three times, then gradually rise to room temperature, and react overnight. The reaction solution was diluted with a large amount of water, the solid was separated, and then repeatedly washed with NaHCO 3 Aqueous solution and methanol wash several times, after drying, purify with hot chlorobenzene solvent, obtain compound (4.3g, productive rate 70%) shown in formula (IV), its chemical reaction equation is:
