Anions and neutral radicals of trialkoxy substituted trioxotriangulene (TOT) derivatives (TOT(O-n-CnH2n+1)) have been synthesized and their temperature dependent polarizationmicroscopy and DSC measurement suggested that they becomes thermotropic liquid crystal. Furthermore, anion of tris(3,4,5-tri(dodecyloxy)phenyl) substituted TOT displays discotic columnar liquid crystalline phase. The liquid crystalline organic molecules developed in this research in which electronic spin and electronic charge is delocalized widely on its molecular backbone had never been reported. The accumulation of the knowledge about this kind of novel organic molecular systems should leads the first step for the realization of the liquid crystal material that could quickly respond to the external stimuli and could be applied to 3D imaging. The result of this research could also contribute to the development of the light functional materials for organic thin layer solar cells and multifunctional materials in which light, electricity, and magnetism are working together, and it is expected to construct a base of new industry in the future.

本文合成了三烷氧基取代三氧三角烯（TOT）衍生物（TOT(O-n-CnH2n+1)）的阴离子和中性自由基，其温度依赖的偏光显微镜和DSC测量表明它们成为热致液晶。此外，三（3,4,5-三（十二烷基氧基）苯基）阴离子取代的TOT呈盘状柱状液晶相。本研究开发的液晶有机分子中，电子自旋和电子电荷在分子骨架上广泛离域的现象尚未见报道。对这类新型有机分子体系知识的积累，将为实现能够快速响应外界刺激并可应用于三维成像的液晶材料迈出第一步。该研究成果还有助于有机薄层太阳能电池的轻功能材料和光、电、磁相结合的多功能材料的开发，并有望在未来构建新的产业基础。
