摘要

为了提高三苯并二恶嗪（TPDO）的溶解度并降低其最低未占分子轨道（LUMO）能级，我们设计、合成并研究了一系列新型亚胺融合 TPDO 衍生物（TPDODIs）。烷基二亚胺基团的引入赋予了 TPDODIs 高溶解性和低于 -3.90 eV 的 LUMO 能级。TPDODIs 在可见光区域也有很强的吸收能力，具有很高的最大摩尔消光系数和荧光量子产率（分别为 0.67 和 0.71）。此外，TPDODIs 还具有热致性液晶行为，表现为纺锤形向列或树枝状纹理。它们的高溶解度和低 LUMO 水平表明，这些材料非常适合用于可溶液加工的 n 型电子器件。

Triphenodioxazine Diimides: Design, Synthesis, and Properties.

To increase solubility and decrease the lowest unoccupied molecular orbital (LUMO) energy levels of triphenodioxazine (TPDO), a novel series of imide-fused TPDO derivatives (TPDODIs) were designed, synthesized, and investigated. The introduction of alkyl diimide groups endows TPDODIs with high solubility and LUMO energy levels below -3.90 eV. TPDODIs also show strong absorption in the visible region with high maximum molar extinction coefficients and high fluorescence quantum yields (0.67 and 0.71, respectively). Moreover, TPDODIs display thermotropic liquid-crystalline behavior as indicated by spindly nematic or dendritic textures. Their high solubility and low LUMO levels suggest these materials are well-suited for solution-processable n-type electronic devices.

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.
