In this article, nanoporous ionic organic networks (PIONs) with a high ionic density (three cation–anion pairs per unit) have been synthesized by a facile SN2 nucleophilic substitution reaction. Owing to the electrostatic and steric effect, those ionic networks with porous channels can stabilize and support gold (Au) nanoparticles (NPs) in 1–2 nm. We find the Au@PION hybrid materials used as a heterogeneous catalyst are highly active, selective, and stable in the aerobic oxidation of saturated alcohols.
