| Abstract |
We prepared a hypercrosslinked porous organic polymer, 1T, and sequentially modified it to 1TC and 1TCS. Carboxylic groups of 1TC were oxidized from methyl groups of 1T and sulfonic acid groups of 1TCS were introduced from 1TC via direct substitution using chlorosulfonic acid. The compounds were characterized by different techniques including infrared spectroscopy, thermogravimetric analysis, X-ray photoelectron spectroscopy, 13C Solid state nuclear magnetic resonance, gas sorption and impedance spectroscopy. Especially, 1TCS showed the highest ammonia capture capability per surface area. To enhance selective NH3 adsorption over water vapor, we coated the surface of 1TCS with hydroxyl-terminated poly(dimethylsiloxane) (PDMS). As a result, 1TCS@PDMS10 showed enhanced NH3 adsorption capacity at the low pressure and hydrophobicity. Detailed contents will be given in the poster presentation. |
