A novel 3D POMOFs based As^III-capped Keggin arsenomolybdate with four V^IV substituted, [As₂^IIIAs^VMo₈^VIV₄^IVO₄₀]₂[Cu^ICu₂^II(pz)₄]₂·9H₂O (1) (pz = pyrazine) was prepared by hydrothermal method and characterized by elemental analysis, IR, TG, XPS, BET, Raman, optical band gap and XRD. Compound 1 represents the first polyoxometalate metal organic frameworks (POMOFs) based [As₂^IIIAs^VMo₈^VIV₄^IVO₄₀]⁵⁻ polyoxoanion and {Cu-pz} complex, which forms a 3D topological network with the Schläfli symbol of {5.6.8}{5².6.7.8²}{5².7².8²}{6.7.8}. Compound 1 displays excellent photocatalytic activity and stability for degradation methylene blue (MB), rhodamine-B (RhB), methyl orange (MO), and Azophloxine (AP) under UV light. The photodegradation reaction kinetic and mechanism of 1 were explored. In addition, the luminescence property of 1 was also investigated.
