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 CO₂ uptake capacity (37.9 cm³ 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.

烷基胺掺入具有固有微孔性的酰胺肟功能化聚合物中以捕集和分离气体

具有内在微孔性（PIM）的mid胺肟官能化聚合物是由PIM-1经羟胺的后合成官能化合成的，并与烷基胺结合加工成化学吸附剂。扩散反射红外傅里叶变换光谱（DRIFTS）研究详细描述了功能化PIM-1与伯胺之间的强相互作用。制备的吸附剂不仅在报告的PIM中显示出最高的CO ₂吸收能力（在0.15 bar和298 K下记录为37.9 cm ³ g ^-1），而且还展示了可调谐，可加工和稳定的聚合物吸附剂设计，可以进行纳米工程设计用于其他气体捕获和分离应用。
