Synthesis of a novel 3D supramolecular hybrid via in situ self-assembly for the degradation of organic dyes

Complex [Cu-I(phen)(2)Cl][Cu-II(phen)(2)Cl](3)(PW12O40)center dot 4DMF (1, phen = 1,10-phenanthroline) was synthesized by the solvothermal method and characterized by IR, TG, XPS and single crystal X-ray diffraction analyses. From the structural analysis of the supramolecular polyoxometalate (POM) 1, 3D supramolecular networks were constructed by the respective segments and polyoxoanions via hydrogen bonding and pi center dot center dot center dot pi stacking interactions. POM 1 contains two types of channels (pore A and pore B) that intersect each other, in which small molecules can be filled. The electrochemical and photocatalytic properties of POM 1 were investigated. POM 1 has an excellent catalytic ability for the degradation of organic dyes, such as Rhodamine B, Methylene Blue and Congo Red.
