A microporous organic polymer bearing 2,2'-bipyridine functional group (MOP-bipy), has been synthesized. After treating with Pd(CH3CN)(2)Cl-2, a composite material Pd/MOP-bipy was obtained. The materials have been characterized by C-13 CP/MAS NMR, FT-IR, PXRD, SEM, TEM, nitrogen adsorption and thermogravimetric (TG) techniques. The content and valence of palladium in Pd/MOP-bipy have been determined by ICP and XPS. The composite material Pd/MOP-bipy exhibits excellent catalytic activity for Suzuki-Miyaura reaction in water and Sonogashira coupling reaction in methanol/water. The catalyst can be recycled at least five times without significant loss of the activity.
