Cover Feature: Tris‐Fused Tetrathiafulvalenes Extended with an Anthraquinoid Spacer as New Positive Electrode Materials for Rechargeable Batteries (Eur. J. Org. Chem. 16/2019)

The Cover Feature shows the windmill‐like molecular array composed of a TTF analogue that can store electricity by accepting anions in the battery cell. The peculiar molecular structure, due to the steric effect by the inserted bulky spacer, result in characteristic windmill‐like molecular array in the neutral state and suppress the solubility in the highest oxidation state by reducing intermolecular Coulomb repulsion. This feature improves the cycle‐life performance, which is often considered as a drawback of the organic batteries. More information can be found in the Communication by Y. Misaki et al.
