| titleOfInvention | A kind of main chain polyester oligomeric porphyrin metal complex and its preparation method and application |
| abstract | The invention relates to a main chain polyester oligomeric porphyrin metal complex, a preparation method and application thereof, and belongs to the technical field of catalyst preparation. The oligomeric porphyrin metal complex is obtained by copolymerizing epoxy-modified porphyrin and acid anhydride, and has the structure shown in formula I. The invention can rapidly prepare porphyrin complexes containing multiple active centers. Compared with the prior art, the complex can control the structure of the oligomerization catalyst by changing the type of porphyrin ligand substituent, the epoxy chain length, and the type of acid anhydride, thereby realizing efficient catalysis of the copolymerization of carbon dioxide and epoxide. The catalyst exhibits the advantages of high activity, high polymer selectivity, high temperature stability, and controllable carbonate content in the catalyzed copolymerization of carbon dioxide and epoxide. |
