Synthesis of a porphyrinic polymer for highly efficient oxidation of arylalkanes in water

• Porphyrin moieties were immobilized into rigid, stable and porous CPF-1.
• CPF-1 was simply metalated to result in a highly active catalyst Mn-CPF-1.
• Mn-CPF-1 exhibits high activity and selectivity in heterogeneous catalysis.
• Mn-CPF-1 is much superior to the homogeneous counterpart.

A highly stable covalent-porphyrinic framework Mn-CPF-1 was synthesized by reaction of cyanuric chloride and tetraphenylamine porphyrin (TAPP) and subsequent metallation. Mn-CPF-1 exhibits remarkable catalytic activity and stability on catalytic oxidation of arylalkanes in water under mild conditions, which is much superior to the homogeneous analog Mn-tetraphenylporphyrin (Mn-TPP) under identical conditions.

A highly stable and porous porphyrinic material CPF-1 has been successfully designed and constructed, which can be easily metalated with manganese ions to realize high catalytic efficiency and stability on oxidation of arylalkanes in water at room temperature.Figure optionsDownload as PowerPoint slide
