A {Cu 6 }-added polyoxometalate cluster-organic framework: synthesis, structure and application as a solid support for enzyme immobilization.

A new two-dimensional {Cu6}-added polyoxometalate cluster-organic framework (Cu-POMCOF) was prepared by a hydrothermal method from lacunary polyoxoanions and was applied as a solid support for immobilizing MP-11 and Cyt c. The biocomposite complex exhibits higher stability and catalytic activity than the original free enzyme.
