The construction of porous organic polymer from 5,10,15,20-tetraphenylporphyrin (TPP) was described using one-pot Friedel-Crafts alkylation reaction. Au was simultaneously loaded on the porphyrin-based polymer denoted as Au/KAPs(DCM-TPP). This polymer-supported Au was fully characterized by many physicochemical methods. It was found to possess BET surface area of 796 m2 g−1, good thermal stability above 250 °C and Au nanoparticles with an average size of 8 nm. It was used as an efficient heterogeneous catalyst for alkyne hydration and alcohol oxidation in water. This Au catalyst exhibited excellent catalytic efficiency and recycling performance without loss of activity at least five times. A new strategy to synthesize polymer-supported Au nanoparticle catalyst was finally provided.
