Two kinds of novel triphenylphosphine‐containing microporous organic polymers are designed and synthesized via palladium‐catalyzed Sonogashira−Hagihara coupling condensation reaction of triphenylphosphine oxide‐ and sulfide‐based monomers with different arylethynylene linkers. The gas adsorption isotherms reveal that these polymers have strong binding affinity for CO 2 with high CO 2 adsorption capacity, although they have moderate Brunauer−Emmett−Teller surface area ranging from 684 to 883 m 2 g −1 . Among the resulting polymers, triphenylphosphine oxide–tris(4‐ethynylphenyl)amine exhibits the highest CO 2 uptake capacity of 2.61 mmol g −1 at 273 K and 1.13 bar with relatively high gas selectivity of 60.2 for CO 2 over N 2 at 273 K.
