Homogeneous catalysis involving metal complexes has been playing important roles in organic transformation, but the difficulty in separation and recycling strongly hinders their commercial applications. Here we describe a facile and universal route for synthesizing porous organic ligands (POLs) via solvothermal polymerization. The POLs were obtained quantitatively, and show high surface area, large pore volume, hierarchical porosity, superior thermal stability, and high concentration of organic ligands. The POL bearing triphenylphosphine supported palladium and rhodium catalysts (Pd/POL-PPh3 and Rh/POL-PPh3) exhibit high activities and excellent recyclabilities in hydroformylation and Suzuki reactions.Particularly, the heterogeneous metal loaded POL-PPh3 catalysts show even higher activities than their corresponding homogeneous analogues. These features should be applied to design and develop a wide variety of efficiently heterogeneous catalysts in organic transformation.
