Front Cover: Perfluorophenyl‐Perfluorophenyl Stacking‐Promoted Aggregation‐Induced Emission Enhancement of Crystalline 5‐Aryloxy‐3H‐Indole (Eur. J. Org. Chem. 9/2021)

Abstract

The Front Cover shows a molecule that emits almost no fluorescence in the dilute solution but does emit blue light due to the overlap of two perfluorophenyl groups in crystalline states. It is expressed by making the castle glow blue by the overlapping of the two hands. We express gratitude to the workers who are devoted to medical care by illuminating the historic building.
