摘　　要：A new porous organic polymer （POP） with high thermal stability and large surface area has been synthesized and applied in the preparation of Pd/POP catalyst. Pd/POP was characterized by XRD, TGA, SEM and TEM. The catalyst consists of highly dispersed palladium nanoparticles of 0.9--4 nm size on POP with a large surface area of 650 m2/g. It presents high catalytic activity for Suzuki-Miyaura and Sonogashira reactions. The catalyst was reus- able for three to five times without significant loss of activity.A new porous organic polymer （POP） with high thermal stability and large surface area has been synthesized and applied in the preparation of Pd/POP catalyst.
