Abstract
A series of conjugated metalloporphyrin polymers (MPP-AMnPs) were synthesized by using inexpensive, environmentally friendly and high-efficiency CuI/N,N-dimethyl glycine as catalytic system, and 5,10,15,20-mesotetra(4-aminophenyl) porphyrin manganese and p-dibromobenzene as building blocks. Scanning electron microscopy, N2 adsorption-desorption isotherms and scanning electron microscopy indicated that the polymers had large surface areas and homogeneous microporous structures. Thermogravimetric analysis showed that the polymers had remarkable thermostability. The catalytic performance of MPP-AMnP was tested by oxidizing cyclic ketones with dioxygen as oxidant. The conversion was high in a mild environment in l,2-dichloroethane solvent at 60 °C. Moreover, MPP-AMnP remained stable in the reaction process and highly catalytically active after ten successive recycles.
