2,7-dibroMo-9,10-dihydrophenanthrene-9,10-dione - Reference Information
| Overview | 2, 7-dibromo-phenanthroquinone is an important pharmaceutical intermediate, such as it can be used to prepare a soluble poly 5, 10-phenanthrene thiophene, Poly 5, 10-phenanthrene thiophene has a large conjugated co-planar structure, than polyfluorene, polysilylfluorene-based and polycarbazole-based polymers have narrow band gaps and meet the requirements of solar cell donor materials; Their structures contain thiophene and carboxyl groups, which will facilitate compatibility with fullerene (PCBM). The above two features make poly (5,10-phenanthrene thiophene) a new type of solar cell material. |
| preparation | the synthesis of 2, 7-dibromo-phenanthrene quinone was as follows: in a three-necked flask, phenanthrene quinone (6.24g,30mmol), concentrated sulfuric acid (50ml), NBS(11.2g,63mmol) was slowly added at 0 C, the reaction was 2 hours, the reaction solution was slowly poured into ice water, filtered, the resulting solid was recrystallized from dimethyl sulfoxide to give 5.6g of 2, 7-dibromo-phenanthroquinone as an orange solid in 50% yield. |
