A new 3D Keggin-POM based metal–organic framework of Cu and H2biim: Assembly and properties of fluorescence and electrochemistry

A new 3D Keggin-based metal–organic framework consisting of two kinds of Cu-H2biim chains, Cu10(H2biim)10(PW12O40)2(OH)4·5H2O 1 (H2biim = 2,2′-biimidazole), has been synthesized under hydrothermal conditions. The TGA and PXRD measurements show that the framework is stable after removal of the guest water molecules. In addition, the luminescent and electrochemical properties of 1 have also been investigated.
