A molecular design for transforming non‐emissive molecules to luminescent dyes is demonstrated. By boron complexation, symmetry of molecular electronic orbitals was drastically changed. As a result, electronic transition between frontier orbitals with the forbidden character was perturbed. Finally, the luminescent property can be induced. In the manuscript, the emission band in the long wavelength region can be successfully detected by employing a small heterocyclic system consisting of pentaazaphenalene. According to the data from optical measurements and quantum calculations, the validity of this strategy is demonstrated. More information can be found in the Full Paper by Kazuo Tanaka et al.

通过硼络合干扰禁忌电子跃迁增强非发光1,3,4,6,9b-五氮杂萘的光吸收和发光性质

演示了将非发射性分子转化为发光染料的分子设计。通过硼络合，分子电子轨道的对称性发生了巨大变化。结果，具有禁忌特征的边界轨道之间的电子跃迁受到干扰。最后，可以诱导发光性质。在手稿中，通过使用由五氮杂萘构成的小型杂环系统，可以成功地检测出长波长区域的发射带。根据光学测量和量子计算的数据，证明了该策略的有效性。可以在田中和雄等人的论文全文中找到更多信息。
