Cover Feature: Surface Studies on the Energy Release of the MOST System 2‐Carbethoxy‐3‐Phenyl‐Norbornadiene/Quadricyclane (PENBD/PEQC) on Pt(111) and Ni(111) (Chem. Eur. J. 25/2023)

The energy storage cycle of the molecular solar thermal (MOST) system has been investigated. In particular, upon irradiation, the energy-lean 2-carbethoxy-3-phenyl-norbornadiene is converted into its energy-rich quadricyclane isomer. The energy-releasing back reaction can be triggered thermally by means of a suitable catalyst surface. The differences in the energy landscapes is visualized by sea level and mountains.
