Polycyclic aromatic hydrocarbons that extend over 2 nm in one dimension are seen as monodisperse graphene nanoribbons, which have attracted significant attention for a broad range of applications in organic electronics and photonics. Herein we report the synthesis of a stable bisthiadiazole-capped pyrene-containing nanoribbon with 18 linearly fused rings (NR-18-TD). Thanks to the presence of alternating tert-butyl and tri-iso-butylsilyl groups, NR-18-TD is highly soluble in organic solvents and therefore its structure and fundamental optoelectronic, redox and electrical properties could be unambiguously established. This work illustrates that NR-18-TD is a promising soluble NR-based n-type semiconductor for applications in organic electronics.
一维上延伸超过 2nm 的多环芳烃被视为单分散石墨烯纳米带，由于其在有机电子学和光子学中的广泛应用而引起了极大的关注。在此，我们报道了一种稳定的双噻二唑封端的含苝的纳米带（NR-18-TD）的合成，该纳米带含有 18 个线性稠合环。由于存在交替的叔丁基和三异丁基硅基，NR-18-TD 在有机溶剂中具有很高的溶解性，因此可以明确确定其结构和基本的光电、氧化还原和电学性质。这项工作表明，NR-18-TD 是一种很有前途的基于 NR 的可溶性 n 型半导体，可用于有机电子学。
