Abstract

Novel all-thiophene-based conjugated porous organic polymers (ThPOP-1 and ThPOP-2) were synthesized through ferric chloride-catalyzed oxidative coupling polymerization at room temperature. ThPOP-1 and ThPOP-2 were characterized via solid-state 13C CP/MAS NMR spectroscopy, Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, and elemental analysis. The sulfur content of the obtained polymers is approximately 36 wt%. The Brunauer–Emmett–Teller specific surface area results of ThPOP-1 and ThPOP-2 are 1050 and 160 m2 g−1, respectively. Carbon dioxide adsorption isotherms show that ThPOP-1 (15.0 wt%) exhibits a larger uptake capacity than ThPOP-2 (4.0 wt%) at 273 K and 1.0 bar. Hydrogen uptake is also excellent for ThPOP-1 (2.23 wt%) at 77 K and 1.0 bar.
