In 2022,Ahmed, Mostafa; Kotp, Mohammed G.; Mansoure, Tharwat Hassan; Lee, Rong-Ho; Kuo, Shiao-Wei; El-Mahdy, Ahmed F. M. published an article in Microporous and Mesoporous Materials. The title of the article was 《Ultrastable carbazole-tethered conjugated microporous polymers for high-performance energy storage》.Application of 6825-20-3 The author mentioned the following in the article:
Conjugated microporous polymers (CMPs) have considered as organic porous polymers featuring combination of p-conjugated skeletons with permanent micro-porosity. In the present study, we report the synthesis of carbazole-tethered conjugated microporous polymers, BC-Py-CMP and BC-BF-CMP, resp., through the Suzuki-Miyaura coupling polymerization of the novel 3,3′,6,6′-tetraboronic-pinacolate-9,9′-bicarbazole (BC-4Bpin) with 1,3,6,8-tetrabromopyrene (Py-4Br) and 3,3′,6,6′-tetrabromo-9,9′-bifluorenylidene (BF-4Br). These CMPs exhibited extraordinary thermal stabilities (up to ca. 694 and 569 °C) and high surface areas (up to ca. 1030 m2 g-1). Moreover, the as-prepared BC-BF-CMP exhibited a high specific capacitance of 260 F g-1 at 0.5 A g-1 and showed outstanding cycling stability, having 89.60% capacitance retention of its authentic capacitance over 6000 cycles. The excellent electrochem. capacitances of the BC-BF-CMP were presumably due to the 9,9′-BF could easily accept one electron, causing the reduced form acquiring greater aromaticity by meeting Huckel′s requirements, as a result improving the electron transporting properties. Such CMPs tend to have tremendous potential to be used as a high-performance supercapacitors in energy storage systems. In addition to this study using 3,6-Dibromo-9H-carbazole, there are many other studies that have used 3,6-Dibromo-9H-carbazole(cas: 6825-20-3Application of 6825-20-3) was used in this study.
3,6-Dibromo-9H-carbazole(cas: 6825-20-3) is used as a pharmaceutical intermediate, and also an important intermediate of synthesizing optoelectronic materials. It has been used as a reagent in the synthesis of P7C3-A20 which is a potent neuroprotective agent.Application of 6825-20-3
