The purpose of this project is to establish solid-state NMR methodology which enables us the detailed analysis of static and dynamic structures of organic amorphous materials. In this study, the structure analysis of organic low-molecular-weight materials and polymers including synthetic and natural rubbers was performed. Among the series of researches, we especially focused on the analysis of materials for organic light-emitting diodes (OLEDs). For a light-emitting OLED material, a clear relationship was obtained between the light-emitting properties and the isomeric states. Since the isomeric states of Alga are difficult by X-ray diffraction experiments, the results obtained in this study clearly show the validity of the structure analysis by solid-state NMR On the basis of the relationship, OLEDs were fabricated from α-Alq3, δ-Alq3, and the mixture powders of α-, γ-, and δ-Alq3 It was found that the devices fabricated from δ-Alq3 and the mixture powders exhibit higher luminescence compared to those from standard α-Alq3. For a hole-transport OLED material, the intermolecular distance was determined by solid-state NMR with a supercycle R26411 pulse sequence. This is a first example, which experimentally determines the hopping distance for the carrier transport of the OLED material.

本项目的目的是建立固体核磁共振方法，使我们能够详细分析有机非晶态材料的静态和动态结构。本研究对有机低相对分子质量材料和聚合物进行了结构分析，包括合成橡胶和天然橡胶。在这一系列研究中，我们特别关注有机电致发光二极管(OLED)材料的分析。对于OLED发光材料，其发光性能与其同分异构态之间存在明显的对应关系。由于X射线衍射实验很难确定藻类的异构态，本研究的结果清楚地表明了固体核磁共振结构分析的有效性。根据这一关系，用α-Alq3，δ-Alq3以及α-，γ-和δ-Alq3的混合粉末制备了有机电致发光器件，发现δ-Alq3和混合粉末制备的器件比标准α-Alq3制备的器件具有更高的发光性能。对于空穴传输的OLED材料，采用固体核磁共振技术，以超循环R26411脉冲序列测定了分子间距离。这是第一个例子，它在实验上确定了OLED材料的载流子传输的跳跃距离。
