Abstract

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 multi-connected aniline precursors. The NCMPs with high N content (11.84 wt%), intrinsic ultramicroporosity (<1 nm) and moderate surface area (485 m2 g-1), show wide-ranging adsorption functionality, e.g. CO2 uptake (11 wt%) and CO2-selectivity over N2 (360, 1 bar), 1.0 wt% H2 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.
