Abstract
AbstractThe reduction product of imine‐based porous organic cage CC1, namely dodecamine organic cage RCC1, was introduced as a novel crosslinker in fabrication of polymeric monolith by ring‐opening polymerization with ethylene glycol diglycidyl ether (EGDGE). Due to the presence of amines in polymeric matrix, poly(RCC1‐co‐EGDGE) monoliths could be employed as dual functional reductant and stabilizer in the formation of gold nanoparticles (AuNPs) on their surface by spontaneous reduction of Au3+ to Au0. The immobilized AuNPs, together with micrometer‐scale macropores of the monolith, provided the feasibility of continuous flow catalysis. Then AuNPs‐immobilized poly(RCC1‐co‐EGDGE) monolith (150 μm i.d. × 28 cm in length) was used as a catalytic microreactor in reduction of 8‐nitroquinoline to 8‐aminoquinoline. The reactant in the outflow completely disappeared, and high‐yield product could be conveniently collected, indicating the promising of RCC1‐based monolithic microreactor in catalysis.
