pH-Directed assembly of four polyoxometalate-based supramolecular hybrids by using tritopic bridging ligand 1, 3, 5-tris-(1-imidazolyl)-benzene: Structures and electrocatalytic properties

pH-Dependent syntheses of four new polyoxometalate-based supramolecular hybrids by using an unusual tritopic bridging ligand. Further, the obtained hybrids show good electrocatalytic activities toward reduction of nitrite molecules.308
