A facile approach to prepare a microporous polycarbazole P-tetra(4-(N-carbazolyl)phenyl)silane network with high CO2 storage and separation properties
A facile approach is designed to prepare a novel conjugated polycarbazole microporous P-tetra (4-(N-carbazolyl)phenyl)silane (P-TCzPhSi) network with a tetra-substituted silicon center by FeCl3 oxidative coupling polymerization. The adsorption isotherm of N-2 reveals that the polymer features a high Brunauer-Emmett-Teller (BET) specific surface area of up to 1856 m(2) g(-1). The polycarbazole network exhibits good hydrogen (2.5 wt%, 77 K, 1.1 bar), carbon dioxide (23.5 wt%, 273 K, 1.1 bar) and methane (2.5 wt%, 273 K, 1.1 bar) uptake ability.
