In 2022,Zu, Yucong; Li, Jiawen; Li, Xilin; Zhao, Tongyi; Ren, Hao; Sun, Fuxing published an article in Microporous and Mesoporous Materials. The title of the article was 《Imine-linked porous aromatic frameworks based on spirobifluorene building blocks for CO2 separation》.Computed Properties of C18H12Br3N The author mentioned the following in the article:
Porous organic frameworks entirely composed of organic building blocks are attracting more and more attention owing to their tunable porosity, lightweight and hydrolytic stability. Three novel porous aromatic frameworks (PAFs) based on the [4 + 3] design strategy have been synthesized from spirobifluorene building block as square node and various triangle nodes resp. via imine condensation. These materials are all semiconductors and permanently microporous amorphous polymer with high thermal stabilities. The Brunauer-Emmett-Teller (BET) surface areas of these PAFs are between 389 and 698 m2/g. More importantly, these frameworks exhibit good CO2 uptake (4.0 mmol/g for PAF-131) and outstanding ideal adsorption selectivities for CO2/N2 (121 for PAF-131) and CO2/CH4 (327 for PAF-131) at 273 K and 1 bar, thus showing that they are good candidates for CO2 capture. After reading the article, we found that the author used Tris(4-bromophenyl)amine(cas: 4316-58-9Computed Properties of C18H12Br3N)
In other references, Tris(4-bromophenyl)amine(cas: 4316-58-9) is often used in the synthesis of porous luminescent covalent–organic polymers (COPs)Computed Properties of C18H12Br3N
