Cover Feature: Zwitterionic Mixed Valence: Internalizing Counteranions into a Biferrocenium Framework toward Molecular Expression of Half‐Cells in Quantum Cellular Automata (Chem. Eur. J. 60/2019)

Molecular expression of quantum cellular automata (QCA) , a promising architecture for molecular computing through current‐free processes, requires one‐redox‐site‐specific Coulomb perturbation to mixed‐valence (MV) compounds. This cover picture represents an original approach to creating MV subspecies through unsymmetrically binding guest anions toward replacing virtual point charges in QCA with real charged substances. The resultant zwitterionic MV series vary the degree of positive charge delocalization by changing the bound anions. More information can be found in the Full Paper by K. Tahara, M. Abe, et al. on page 13728.
