Embedding main group elements into the π-scaffold of linearly-fused hexaarenes enables fine-tuning of their optoelectronic properties in solution and in the solid state. Phosphorus leads to the best electron-accepting properties and increases fluorescence quantum yield in solution, silicon maximizes emission in the solid-state, whereas nitrogen leads to the smallest bandgap and promotes stronger intermolecular interactions. These findings offer key insights into structure-property relationships driven by main-group elements, establishing new design principles for the development of improved functional organic materials.
将主族元素嵌入线性稠合六芳烃的π-骨架中，可以在溶液和固态中对其光电性质进行微调。磷具有最佳的电子接受性能，并提高了溶液中的荧光量子产率；硅使固态发射最大化；而氮导致最小的带隙并促进更强的分子间相互作用。这些发现为理解主族元素驱动的结构-性质关系提供了关键见解，为开发改进的功能有机材料建立了新的设计原则。
