Abstract: The 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 Au-0. 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 mm i.d. x 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.
