Design and Synthesis of Supramolecular Polymer Network Equipped with Pd-porphyrin: An Efficient and Recoverable Heterogeneous Catalyst for C–C Coupling Reactions

The present study aimed to explain a modern and attractive protocol for synthesizing hypercross-linked conjugated supramolecular polymer network contains palladium(II) porphyrin based on calix[4]resorcinarene as an efficient heterogeneous catalyst. Thus, characterizations were conducted by using spectroscopic methods including powder X-ray diffraction, energy dispersive spectroscopy, scanning electron microscopy, FT-IR, and UV–Vis spectroscopy. In addition, catalytic activity of Pd-porphyrin@polymer was evaluated for C–C coupling reactions. The catalyst demonstrated an excellent activity, which is highly potential for forming new bond under mild conditions. The synthesis of a novel, green and recoverable heterogeneous catalyst by grafting Pd-porphyrin on the surface of polymeric calix[4]resorcinarene for the synthesis of C–C coupling reactions.
