A novel microporousorganic polymer framework with built-in metal sites in the skeleton has been synthesized by the Sonogashira–Hagihara reaction using salen-palladium as building units. The new microporousorganic polymer possesses a high BET surface area, large pore volume, good stability and acts as a highlyefficientrobust recyclable heterogeneous catalyst towards carbon–carbon coupling reactions
