Widely applied automotive color pigments based on perylene bisimide have been utilized by many groups to create extended one‐dimensional π stacks by self‐assembly. In their Full Paper on page 13665 ff. , F. Würthner et al. report on the application of sterically demanding groups to terminate self‐assembly at the dimer stage. Only in highly nonpolar aliphatic solvents, a rather unusual growth into larger self‐assembled structures is observed.
