摘要

Using Keggin heteropolyoxometalate H3PW12O40 as the template, a new host-guest POM-MOF hybrid material formulated as (CH3NH2CH3)[Cu-2(TPB)(2) (PW12O40)]. 4DMF. 6H(2)O (1) has been successfully synthesized under solvothermal conditions. Complex 1 is characteristic of a 3D host framework constructed from Cu+ ions and TPB ligands and containing different types of one-dimensional channels. The larger channels along the c axis are occupied by Keggin polyoxoanions as guests, while the narrower ones along the [110] direction are available to accommodate solvent molecules and counter dimethylamine cations. Complex 1 shows ultrahigh thermal stability and permanent porosity. In addition, dye adsorption and photocatalytic properties of 1 have been investigated. The results indicated that complex 1 is not only a good heterogeneous photocatalyst for the degradation of MO-, but also selectively captures MB+ from binary mixtures of MB+/MO-, MB+/R6G(+) or MB+/RhB+.
