Nitrogen-rich conjugated microporous polymers (NCMPs) have attracted great attention in recent years owing to their polarity, basicity, and ability to coordinate metal ions. Herein, three NCMPs, structurally close to polyaniline, were facilely synthesized via chemical oxidative polymerization between multiconnected aniline precursors. The NCMPs with high N content (11.84 wt %), intrinsic ultramicroporosity (<1 nm), and moderate surface area (485 m g) show wide-ranging adsorption functionality, e.g., CO uptake (11 wt %) and CO-selectivity over N (360, 1 bar), 1.0 wt % H storage, as well as 215 wt % iodine vapor uptake at ambient pressure. Moreover, these NCMPs act as support for palladium catalysts and can maintain >94% activity in Suzuki-Miyaura coupling reactions after six continuous runs.
富氮共轭微孔聚合物（NCMPs）由于其极性、碱性和配位金属离子的能力，近年来受到了极大的关注。本文通过多连接苯胺前体之间的化学氧化聚合，简便地合成了三种结构上接近聚苯胺的 NCMPs。具有高氮含量（11.84wt%）、本征超微孔（<1nm）和适度表面积（485m²/g）的 NCMPs 具有广泛的吸附功能，例如 CO 吸附（11wt%）和 CO 对 N 的选择性（360，1bar）、1.0wt%的 H 储存以及在常压下 215wt%的碘蒸气吸附。此外，这些 NCMPs 可用作钯催化剂的载体，在六次连续运行后，Suzuki-Miyaura 偶联反应的活性仍保持>94%。
