【摘要】 本文用羟基取代四苯基卟啉锰通过醚键与聚苯乙烯树脂键联，合成了一类高分子负载化锰卟啉化合物。经ＥＳＲ、ＩＲ、ＵＶ－ｖｉｓ散射光谱等测定证实其结构。本文同时考察了它们对烯烃环氧化反应的催化活性，结果表明，负载化金属卟啉在催化烯烃环氧化反应中能集均相和多相催化的优点于一体，不仅催化剂稳定性增强，而且易于分离和重复使用。更多还原

【Abstract】 Metalloporphyrins can catalyse oxidations similar to those brought about by cytochrome P450.Immobilization of metalloporphyrins can remarkably improve the catalytic properties of them and for this reason they have received much attention in recent years. The synthesis of a series of polymer supported manganese (Ⅲ) porphyrin is described.Hydroxy-substituted tetraphenyl porphyrins manganese (Ⅲ) were attached to polystyrene resins via ether bond.ESR.IR and UV Vis diffuse reflection spectra were used to characterize the materials.By anchoring manganese (Ⅲ) porphyrins to polystyrene resins,the catalytic activity and stability of the manganese porphyrins were greatly enhanced.It was shown that polymer supported manganese (Ⅲ) porphyrins are effective catalysts for olefin epoxidation and can be reused.更多还原
