Porphyrin ligands and phthalocyanine ligands play a very important role in organometallic chemistry due to their unique structure and electronic properties. They can adjust the electronic structure, catalytic activity and selectivity of metal centers by coordinating with metal ions. Especially in the fields of catalysis, optoelectronic materials, sensors and medicine, metal-porphyrin complexes and metal-phthalocyanine complexes have broad application prospects. The unique structure of these ligands makes them highly selective and active in many reactions, and they are important catalysts and materials.
