Facile synthesis of a conjugated microporous polymeric monolith via copper-free Sonogashira-Hagihara cross-coupling in water under aerobic conditions

A conjugated microporous polymer was synthesized via a modified Sonogashira-Hagihara cross-coupling reaction under aerobic conditions in water and in the absence of copper. These conditions allowed the directing of the CMP format during synthesis into a monolithic structure. Post-modification of the polymer with thiol-yne chemistry followed by Ag^I uptake led to a catalytically active material for a heterocyclization reaction.
