A new type melamine-based porous organic polymers (SZU-1) has been synthesized with melamine and 2,2′-bipyridyl-5,5′-dialdehyde by a one-pot method and fully characterized. Divalent palladium salts were coordinated to this polymer network which successfully catalyzed the nucleophilic addition reaction of arylboronic acids to aromatic aldehydes. With only 1.0 mol% heterogeneous catalyst loading, high reaction yields (> 85%) can be achieved in most cases. The scope of substrates was also investigated and the catalyst showed universal applicability. The loose and porous melamine-based porous organic polymers (SZU-1) are synthesized by melamine and 2,2′-bipyridyl-5,5′-dialdehyde. The performance of SZU-1 was characterized and most of the substrates achieved high yield (> 85%) in the catalytic performance test.
