摘要

A new arsenotungstate, [H2AsW11O39][Cu-3(2,2'-bipy)(3)(H2O)(2)(OH)]center dot 2H(2)O (1) (2,2'-bipy = 2,2'-bipyridine), has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, UV-Vis, TG and single-crystal X-ray diffraction. The compound 1 represents the first example of copper-bipyridine complexes substituted mono-vacant Keggin polyoxotungstate containing As-V. Compound 1 exhibits fluorescent property at room temperature. Furthermore, compound 1 has been used as a solid bulk-modifier to fabricate bulk-modified carbon paste electrodes (1-CPE) by direct mixing. The electrochemical behavior and electrocatalysis of 1-CPE have been studied in detail.
