Linearly-fused polyarenes are an important class of compounds with high relevance in materials science. While modifying the shape and size represents a common means to fine-tune their properties, the precise placement of heteroatoms is a strategy that is receiving an increasing deal of attention to overcome the intrinsic limitations of all-carbon structures. Thus, linearly-fused diphosphaarenes recently emerged as a novel family of molecules with striking optoelectronic properties and outstanding stability. However, the properties of diphosphaarenes are far from being benchmarked. Herein, we report the synthesis, phosphorus post-functionalization and properties of new diphosphapentaarene derivatives. We describe their synthetic limitations and unveil their potential for optoelectronic applications.
线性稠合多芳烃是一类在材料科学中具有重要应用价值的化合物。改变其形状和大小是精细调控其性能的常用手段，而精确放置杂原子则是一种越来越受到关注的策略，旨在克服全碳结构的固有局限性。因此，最近线性稠合二膦芳烃作为一类具有显著光电性能和优异稳定性的新型分子而崭露头角。然而，二膦芳烃的性质远未达到基准水平。在此，我们报告了新型二膦戊芳烃衍生物的合成、磷后功能化及其性质。我们描述了它们的合成限制，并揭示了它们在光电应用方面的潜力。
