Amidoxime functionalized polymers of intrinsic microporosity (PIMs) are synthesized from postsynthetic functionalization of PIM‐1 with hydroxylamine and processed into chemisorbents with alkylamine incorporation. Strong interaction between functionalized PIM‐1 and primary amines is characterized in detail by diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) study. As‐prepared sorbents not only show the highest CO 2 uptake capacity (37.9 cm 3 g −1 at 0.15 bar and 298 K) recorded in reported PIMs, but they also demonstrate tunable, processable, and stable polymeric sorbent design, which can be nanoengineered for other gas capture and separation applications.
