摘要 本文采用改进的硅烷化方法合成了一系列具有不同饱和磁化强度的纳米颗粒键合金属卟啉。在地磁场（5×10−5T）下，随着饱和磁化强度的增加，这些纳米颗粒键合金属卟啉催化碘代环己烷氧化环己醇的产率增长率依次为：铁卟啉>锰卟啉>钴卟啉。 采用改进的硅烷化方法合成了具有不同饱和磁化强度的纳米颗粒键合金属卟啉。在地磁场（5 × 10−5T）下，随着饱和磁化强度的增加，这些纳米颗粒键合金属卟啉催化碘酰苯环己烷氧化反应中环己醇收率的增长顺序为铁卟啉>锰卟啉>钴卟啉。
AbstractIn this paper, a series of nanoparticle bonded metalloporphyrins with different saturation magnetization were synthesized by a modified silanation method. Under geomagnetic field (5 × 10−5T), with the increase of the saturation magnetizations, the growth rate of yields of cyclohexanol in the cyclohexane oxidation with iodosylbenzene catalyzed by these nanoparticle bonded metalloporphyrins followed the order of ironporphyrin > manganeseporphyrin > cobaltporphyrin.Graphical AbstractA series of nanoparticle bonded metalloporphyrins with different saturation magnetization were synthesized by a modified silanation method.
