Hierarchical self‐organization of bis(merocyanins), as shown in the cover picture, lead in the first step to helical polymers (top), which come together to form rod‐type aggregates in methylcyclohexane (middle right). These arrange finally at higher concentrations into a hexagonal dense packing (bottom). As F. Würthner et al. describe in their Communication on page 3247 ff., gels and liquid‐crystalline films can be generated in this way with unusual textures, as shown in the background.
