In the organic electroluminescent (EL) display devices, thermally stable materials are demanded for the coming full-color display. New triphenylamine derivatives having a spirocyclic aromatic skeleton are devised for the efficient hole-transport material in the multi-layered devices.Our research efforts led to the following results.1. Various types of new triphenylamines having a mono- or di- spirocyclic structure were successfully prepared. They showed all high thermal stability as indicated by glass transition temperatures over 100℃ required for practical use.2. EL characteristics of these amines depended on the organic structure, Among them, dibenzochrysene (DBC) type was incidentally found to show exceedingly high luminance. It turned out to be due to self-emissive nature, thus being the most promising for practical application.3. Our findings on the synthesis, structure and properties of spiro compounds are interesting in organic chemistry as well as for future development in organic EL devices-(see several papers).

在有机电致发光（EL）显示器件中，热稳定性材料是未来全色显示所必需的。本论文设计了一类新型的具有螺环芳香骨架的三苯胺类化合物作为多层结构器件中的空穴传输材料，取得了以下研究成果.合成了具有单螺环或双螺环结构的新型三苯胺类化合物.玻璃化转变温度超过100℃，表明它们具有较高的热稳定性.这些胺的电致发光特性取决于有机结构，其中，二苯并黄嘌呤（DBC）型被偶然发现显示出非常高的亮度。这是由于自发光的性质，因此是最有希望的实际应用。我们对螺环化合物的合成、结构和性质的研究结果在有机化学以及有机EL器件的未来发展中是有趣的（见几篇论文）。
