Two hydrophobic pyrene‐based hypercrosslinked microporous resins (ZLYs) with intrinsic hydroxyl groups on the pore‐walls have been prepared by condensation of 1,3,6,8‐tetrakis(p‐formylphenyl)pyrene (TFPPy) with phloroglucinol (L 1 ) or 1,5‐dihydroxynaphthalene (L 2 ). The resulting porous networks exhibited high thermal stabilities and moderate Brunauer–Emmett–Teller surface area with 647 and 243 m 2 g −1 respectively. The experiments showed that the weak interactions between CO 2 and the intrinsic hydroxyl groups on the pore‐wall of the resins could enhance CO 2 uptake and CO 2 /CH 4 selectivity. © 2018 Wiley Periodicals, Inc.
