Abstract

Mesoporous polymeric organic frameworks (mesoPOF)s have been synthesized through surfactant mediated polymerization of phlorglucinol (1,3,5- trihydroxybenzene) and terephthalaldehyde under solvothermal conditions. The materials contain bound surfactant and exhibit hydrophobic properties. The mesoPOFs present high surface areas up to 1000 m 2 g -1 and have pores of several size ranges from micropores to large mesopores depending on the amount of surfactant used. The adsorption uptakes of CO 2, C 2H 6, and CH 4 measured at 273 K at 1 bar are linearly correlated to the micropore volume. The mesoPOFs display high adsorption selectivity of C 2H 6 over CH 4 by a factor of 40, and this property is dictated by their pore diameter.
