Understanding structural defects as potential advantages is key for nanographene technology. In their Research Article on page 7139, E. Maçôas, A. G. Campaña, and co‐workers show how the introduction of a carbonyl‐substituted heptagonal ring (tropone ring) into a nanographene ribbon increases the efficiency of upconverted emission by two‐photon excitation in comparison with a defect‐free analogue. Therefore, structural defects are shown to be beneficial for specific nanographene applications, from materials science to biomedical applications.
