| 研究実績の概要 |
For the final year, the ionic porous organic polymers (i-POPs) have been successfully synthesized via a facile Friedel-Crafts alkylation reaction and cost-effective process. The i-POPs were constructed through the natural building units (4,4'-bis(chloromethyl)-1,1'-biphenyl, BP) as a crosslinking agent and ionic building unit (1,1'-([1,1'-biphenyl]-4,4'-diyl)bis(N,N,N-trimethylmethanaminium) chloride, BPTM) under solvothermal conditions by FeCl3 as the catalyst. With the increment of the ionic unit, the i-POP-1, i-POP-2, and i-POP-3 were successfully synthesized under the same condition. The i-POPs indicated excellent porosity including the highest BET surface area (1491-1753 m2 g-1) and pore volume (2.19-2.94 cm3 g-1) among all reported ionic frameworks. At 273 K and 1 bar, i-POP-1 displayed high carbon dioxide uptake of 14.0 wt%.
