项目摘要

It is well known that liquid crystals have been very actively investigated only as imaging materials. Since the application for liquid crystal display (LCD) is too outstandingly useful, the other possibilities based on the liquid crystalline state itself may be neglected.In this research group, we have stood on the viewpoint which is totally different from the conventional thinking method as "liquid crystals=application to LCD." Hence, we have studied not on the conventional liquid crystals for LCD but on novel liquid cryatals unknown so far.At this present time, most of the liguid crystals known are pure organic compounds. Nevertheless, we have synthesized different types of liquid crystals (LCs) : discotic LCs which molecular shapes are disk-like, metallomesogens which contain metals, hydrogenbonding LCs, ionic LCs, and so on. Although these investigations may be regarded as heretical from the conventional LC research works, very sueful novel functionalities like as high-conductivity, magnetism, and so on have been found in these materials.Researchers of metallomesogens in Japan tend to represent their works in their own inherent conferences and/or sessions because of novelty of this field. We had no opportunity to discuss with all together at the same place. Hence, we proposed to make this research group named as "Syntheses and Functionalities of Metallomesogens" for two years from 1997 to 1998. In this research group, we could meet all together and discuss about the new fields of LCs at the first time. As the results, we have reached to our common consensus that great development of novel functional LC materials can be expected on three new expansive fields : (i) metallomesogens (including both thermotropic and lyotropic LCs), (ii) discotic LCs and high-conductive LCs, and (iii) hydrogenbonding LCs and ionic LCs. We strongly believe that these three fields can become future-promising mesophase chemistry.

众所周知，液晶仅作为成像材料进行了非常积极的研究。由于液晶显示器（LCD）的应用过于突出，基于液晶状态本身的其他可能性可能被忽略。在本课题组中，我们站在与传统思维方式完全不同的观点上，即“液晶= LCD的应用”。“因此，我们研究的不是传统的LCD液晶，而是迄今为止未知的新型液晶。目前，大多数已知的液晶都是纯有机化合物。然而，我们已经合成了不同类型的液晶（LC）：分子形状为盘状的分散液晶、含金属的金属介晶、氢键液晶、离子液晶等，虽然这些研究可能被认为是传统液晶研究工作的异端，但非常有用的新功能，如高导电性，磁性，由于这一领域的新奇，日本的金属介晶研究人员倾向于在自己固有的会议和/或会议上发表他们的作品。我们没有机会在同一个地方一起讨论。因此，我们提议将这个研究小组命名为“金属介晶的合成与功能”，从1997年到1998年为期两年。在这个研究小组里，我们可以第一时间聚在一起讨论液晶的新领域。因此，我们已经达成了共识，可以预期在三个新的广阔领域中的新型功能LC材料的巨大发展：（i）金属介晶（包括热致和溶致LC），（ii）双金属LC和高导电LC，和（iii）氢键LC和离子LC。我们坚信这三个领域可以成为未来有前途的中间相化学。
