Titelbild: Supramolecular Self‐Assembly as a Tool To Preserve the Electronic Purity of Perylene Diimide Chromophores (Angew. Chem. 12/2023)

A supramolecular chromophore cube based on perylene diimides (PDIs) is reported by Sascha Feldmann and co-workers in their Research Article (e202216729). The rigid and shape-persistent cage preserves the electronic purity of its PDI constituents and enables the observation of delayed fluorescence because of its bright excited multimer state, acting as an excitation reservoir. Self-assembly can thus serve as a powerful tool for controlling electronic properties in molecular electronics devices.
