A porphyrin-based polymer with high surface area was synthesized using 5,10,15,20-tetraphenylporphyrin through a one-pot Friedel–Crafts alkylation reaction. Pd(II) was successfully supported on this polymer. This strategy provides an easy approach to produce highly stable Pd–porphyrin-based polymer. The resulting Pd catalyst was characterized using Fourier transform infrared and X-ray photoelectron spectroscopies, thermogravimetric analysis, scanning and transmission electron microscopies and N2 adsorption–desorption measurements. This porphyrin-based polymer-supported Pd was used as a heterogeneous catalyst for Suzuki–Miyaura coupling reaction in water. The results demonstrated that this Pd catalyst indeed exhibited excellent catalytic activity and recycling performance in water, even for inactive aryl chloride substrate. A new heterogeneous strategy for catalyzing the Suzuki–Miyaura reaction in water is provided.
