Inside Back Cover: A Memristive Element Based on an Electrically Controlled Single‐Molecule Reaction (Angew. Chem. Int. Ed. 28/2020)

A single‐molecule memory element can be electrically controlled by using two distinct reaction mechanisms as reported by K. Moth‐Poulsen, J. Hihath, and co‐workers in their Research Article on page 11641. By using separate electrically controllable reactions for the forward and reverse reactions, the bistable norbornadiene–quadricyclane system can be set in either state. The device can be switched through multiple cycles when a square‐wave voltage signal is applied to the molecule. Each state has a unique conductance value allowing the system to act as a switch or memory device.
