Inside Back Cover: Electrical Network of Single‐Crystalline Metal Oxide Nanoclusters Wired by π‐Molecules (Angew. Chem. Int. Ed. 42/2014)

Abstract

In a mixed‐valence polyoxometalate electrons are usually delocalized within the cluster anion because of the low intercluster interaction. In their Communication on R. Tsunashima et al. show how mixed‐valence polyoxometalate clusters can be electrically wired together by cationic π‐molecules of tetrathiafulvalene derivatives. The electron‐transport characteristics of the single crystal arise from electron hopping through the strong interactions between the clusters and cationic π‐molecules.

Ultrafast Oxidative Desulfurization of Diesel Fuels by Mass Transfer Enhancement of Polyoxometalate Modified Alumina Catalysts

“…Polyoxometalates (POMs) are a kind of anionic metal oxides and they often can incorporate elements Nb, Mo, V, or W in their highest oxidation states into their structures. − The POMs show specific structural prototypes as well as various sizes, characteristic physical properties, and multiple applications in catalysis, − medicine, electrochemistry, photochromism, and magnetism . Polyoxotungstates have shown great oxidative properties due to the presence of high-valent W VI , and the corresponding W-peroxo species can be generated in the presence of H 2 O 2 , which can oxidize the substrate.…”
