摘要

我们成功合成了两种掺硼分子碳（BMC），其特点是在 C20B 或 C28B 多环 π 骨架中嵌入了一个正式的硼插入戊烯（BP）。尽管它们的共轭结构尺寸较小，但都表现出不同寻常的宽光吸收、窄能隙和电子接受能力，以及具有伪 4π 电子的局部反芳香性。正如所披露的那样，这些引人入胜的物理性质在很大程度上得益于 BP 子结构中的硼原子和五角环，从而证明了将这种 BP 加入多环 π 系统的重要性。

Boron-Doped Molecular Carbons Bearing a Formal Boron-Inserted Pentalene: Synthesis, Electronic Structures and Properties

Two boron-doped molecular carbons (BMCs), featuring one formal boron-inserted pentalene (BP) embedded into the C₂₀B or C₂₈B polycyclic π-skeleton, were successfully synthesized. Despite their small-size conjugated structures, both of them exhibit unusual broad light absorption, narrow energy gaps, and electron-accepting ability, as well as local antiaromaticity with pseudo 4π electrons. As disclosed, these intriguing physical properties are significantly contributed by the boron atom and pentagonal ring in the BP substructure, thus demonstrating the importance of such BP incorporation into polycyclic π-systems.

期刊介绍： Organic Letters invites original reports of fundamental research in all branches of the theory and practice of organic, physical organic, organometallic,medicinal, and bioorganic chemistry. Organic Letters provides rapid disclosure of the key elements of significant studies that are of interest to a large portion of the organic community. In selecting manuscripts for publication, the Editors place emphasis on the originality, quality and wide interest of the work. Authors should provide enough background information to place the new disclosure in context and to justify the rapid publication format. Back-to-back Letters will be considered. Full details should be reserved for an Article, which should appear in due course.
