Metalloporphyrin-Based Porous Coordination Polymers: Synthesis, Served as Heterogenous Catalysts and Dye Scavengers

Six metalloporphyrin-based porous coordination polymers, Mn-II(TCP)-Mn-II (CP1), Fe-III(TCP)-Fe-III (CP2), Co-II(TCP)-Co-II (CP3), Ni-II(TCP)-Ni-II (CP4), Cu-II(TCP)-Cu-II (CP5) and Zn-II(TCP)-Zn-II (CP6), (TCP = 5,10,15,20-tetra(4-(phenoxy-4-yl)butanoic acid)porphyrin tetravalent anion) were prepared and characterized. CP1, CP2, CP3, CP4 and CP6 are amorphous aggregation supported by SEM, TEM and powder XRD. CP5 is a small particles aggregation with lower crystallinity. These coordination polymers exhibit effective dye scavenging and catalytic activities toward the oxidation of alkylbenzene to ketones, and can be reused by filtration with slight decreasing of catalytic activities.
