《Benzimidazole-based hyper-cross-linked poly(ionic liquid)s for efficient CO2 capture and conversion》 was published in Chemical Engineering Journal (Amsterdam, Netherlands) in 2020. These research results belong to Sang, Yafei; Huang, Jianhan. Name: 1,4-Bis(bromomethyl)benzene The article mentions the following:
Porous materials with high Brunauer-Emmett-Teller (BET) surface area (SBET) and abundant ionic active sites facilitate efficient CO2 capture and conversion. Herein, a kind of novel benzimidazole-based hyper-cross-linked poly(ionic liquid)s (HPILs) were developed via the hyper-crosslinking strategy and the as-prepared HPILs possessed high SBET (485-780 m2/g), plentiful micro/mesoporosity, and abundant ionic active sites. The HPILs showed noteworthy CO2 uptake (79-143 mg/g at 273 K and 1.0 bar), moderate isosteric heats (32-45 kJ/mol), and acceptable CO2/N2 selectivity (IAST: 23-46). Intriguingly, HPILs-Cl-2 exhibited excellent catalytic activity for CO2 cycloaddition and 99% of propylene oxide was successfully converted to cyclic carbonates under mild conditions (70°, 0.1 MPa CO2, 9 h). This synthetic strategy is of great importance for the functionalized hyper-cross-linked polymers and the synthesized HPILs are promising for efficient CO2 capture and conversion under mild conditions.

1,4-Bis(bromomethyl)benzene(cas: 623-24-5) belongs to organobromine compounds.Depending on the type of carbon to which the bromine is bonded, organic bromide could be alkyl, alkenyl, alkynyl, or aryl. Alkyl bromides are mainly used as alkylating agents and also find application as a solvent to extract oil from seeds and wool. Name: 1,4-Bis(bromomethyl)benzene
