资源简介：
A new polyoxometalate (POM)-templated 3-D copper(II)-triazole framework [Cu<sub>10</sub>(trz)<sub>10</sub>(OH)<sub>6</sub>(Cl)<sub>4</sub>][H<sub>3</sub>PW<sub>12</sub>O<sub>40</sub>]·2H<sub>2</sub>O (trz = 1,2,3-triazole) has been synthesized and characterized by single crystal X-ray diffraction and other routine methods. The 3-D POM/copper(II)-triazole hybrid framework with a 1-D channel possesses a <i>pcu</i> topology under the template of bulk Keggin-type phosphotungstate. As a new kind of peroxidase mimetic, the new compound effectively catalyzed oxidation of 3,3′,5,5′-tetramethylbenzidine (TMB) in the presence of H<sub>2</sub>O<sub>2</sub>. The electrostatic interactions and hydrogen bonds/π-π stacking interactions among TMB, trz, and phosphotungstate are responsible for the enhancement of peroxidase-like activity. In addition, application for colorimetric sensing of H<sub>2</sub>O<sub>2</sub> is also explored; the new compound exhibits a wide linear range (1–80 μM), low detection limit (0.21 μM), and fast response (2 min).
