Abstract
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.

封面艺术作品可视化二聚体n -异三角烯在螺旋楼梯前反映其螺旋手性。蓝色球体代表氧化还原活性氮，连接的充满活力的途径象征电荷转移，导致p共轭螺旋烯主链实现混合价态。发光的橙色螺旋说明了该化合物发射圆偏振光的能力，这一特性与未来低环境影响的热带应用有关。阅读Dirk M. Guldi， Milan Kivala等人的研究文章（e202423516）。
