Outside Front Cover: Helically Chiral Mixed‐Valence Systems Comprising N Heterotriangulenes: Stabilization of the Cationic Species by π Expansion (Angew. Chem. Int. Ed. 16/2025)
The cover artwork visualizes the dimeric N-heterotriangulene in front of a spiral staircase reflecting its helical chirality. The blue spheres represent the redox-active nitrogens, the connecting vibrant pathway symbolizes the charge transfer leading to a mixed-valence state enabled by the p-conjugated helicene backbone. The glowing orange helix illustrates the compound's ability to emit circularly polarized light, a property relevant to future chiroptical applications with low environmental impact.
