A series of pyridine functionalized porous organic polymers (POPs‐Py&PPh₃) have been synthesized by polymerizing tris(4‐vinylphenyl)phosphane and 4‐vinylpyridine. The pyridine moieties in the copolymer materials contribute to CO₂ adsorption and promote the subsequent conversion of CO₂. The POP supported Ru catalyst (Ru/POP₃‐Py&PPh₃) shows a high catalytic activity (TON up to 710) in the N‐formylation of various primary and secondary amines with CO₂/H₂, affording the corresponding formamides in good yields (55–95%) under mild reaction conditions. The heterogeneous catalyst can be easily separated from the reaction system and reused for at least eight cycles in the N‐formylation of morpholine.

具有吡啶功能的双功能Ru负载多孔有机聚合物：可回收的胺与CO2和H2形成胺的N-甲酰化催化剂

通过聚合三（4-乙烯基苯基）膦和4-乙烯基吡啶，合成了一系列吡啶官能化的多孔有机聚合物（POPs-Py＆PPh ₃）。共聚物材料中的吡啶部分有助于CO ₂吸附并促进随后的CO ₂转化。POP负载的Ru催化剂（Ru / POP ₃ -Py＆PPh ₃）在各种伯胺和仲胺与CO ₂ / H ₂的N-甲酰化反应中表现出很高的催化活性（TON高达710）。，在温和的反应条件下，以良好的收率（55-95％）提供相应的甲酰胺。异质催化剂可以轻松地从反应系统中分离出来，并在吗啉的N-甲酰化反应中重复使用至少八个循环。
