In 2019,ChemPlusChem included an article by Mohamed, Mohamed Gamal; El-Mahdy, Ahmed F. M.; Ahmed, Mahmoud M. M.; Kuo, Shiao-Wei. Quality Control of 3,6-Dibromo-9H-carbazole. The article was titled 《Direct Synthesis of Microporous Bicarbazole-Based Covalent Triazine Frameworks for High-Performance Energy Storage and Carbon Dioxide Uptake》. The information in the text is summarized as follows:
In this study a series of bicarbazole-based covalent triazine frameworks (Car-CTFs) were synthesized under ionothermal conditions from [9,9′-bicarbazole]-3,3′,6,6′-tetracarbonitrile (Car-4CN) in the presence of molten zinc chloride. Thermogravimetric and Brunauer-Emmett-Teller analyses revealed that these Car-CTFs possessed excellent thermal stabilities and high sp. surface areas (ca. 1400 m2/g). The electrochem. performances of this Car-CTF series, investigated by using cyclic voltammetry, showed a highest capacitance of (545 F/g at 5 mV/s), which also exhibited excellent columbic efficiencies of 96.1% after 8000 cycles at 100μA/0.5 cm2. The other Car-CTF samples displayed similar efficiencies. Furthermore, based on CO2 uptake measurements, one of the series showed the highest CO2 uptake capacities: 3.91 and 7.60 mmol/g at 298 and 273 K, resp. These results suggest a simple method for the preparation of CTF materials that provide excellent electrochem. and CO2 uptake performance. In the experiment, the researchers used many compounds, for example, 3,6-Dibromo-9H-carbazole(cas: 6825-20-3Quality Control of 3,6-Dibromo-9H-carbazole)
3,6-Dibromo-9H-carbazole(cas: 6825-20-3) is used as a reagent in the synthesis of P7C3-A20 which is a potent neuroprotective agent. And it has been used in the preparation of N-(2-hydroxyethyl)-3,6-dibromocarbazole.Quality Control of 3,6-Dibromo-9H-carbazole
