化学修飾型ナフチレン環状分子の設計・合成

第一项研究描述了用于单层OLED的亚芳基大环的开发，使一种材料能够在电子和空穴传输层（ETL和HTL）中起作用，以及作为主体材料的发光层（EML）。结构-性能关系的研究揭示了在单层OLED中使用的亚芳基大环作为基础材料的要求。在这样的单层OLED中，用绿色Ir（ppy）3发射体记录到出乎意料的高EQE值，表明已经实现了几乎定量的电光转换。在第二个研究中，我们通过一锅法、交叉偶联大环化反应合成了一系列氮嵌入的[n] CMP（n = 6，8，10，12和14），并对其基本性质进行了研究。通过X射线晶体学分析揭示了结晶固态中的所有大环结构，表明整体大环结构发生了显著变化;这取决于亚芳基单元的数量。溶液相分析表明存在灵活的大环结构。

The first study describes the development of arylene macrocycles for the single-layer OLED, enabling one material to function in electron and hole transport layers (ETL and HTL), as well, an emission layer (EML) as a host material. The structure-performance relationship studies revealed the requirement for the arylene macrocycles to be utilized in the single-layer OLED as a base material. An unexpectedly high EQE value was recorded with a green Ir(ppy)3 emitter in such a single-layer OLED, indicating nearly quantitative electro-optical conversion has been achieved. The results indicated the infinite possibilities of arylene macrocycles for the future development in the organic electronics.In the second study, a series of nitrogen-embedded [n]CMPs (n = 6, 8, 10, 12 and 14) was synthesized via one-pot, cross-coupling macrocyclization and their fundamental properties were clarified. All the macrocyclic structures in the crystalline solid state were revealed by X-ray crystallographic analysis, showing that the overall macrocyclic structures changes dramatically; depending on the numbers of arylene units. The solution-phase analyses showed the presence of flexible macrocyclic structures.
