This Small Business Innovation Research (SBIR) Phase I project aims to test the feasibility of developing families of complex liquid crystal molecules that offer previously unobtainable material properties; advanced electro-optic capabilities in particular. For decades, predominant liquid crystal molecules have been variants on simple rod shapes. Radically new liquid crystal molecules (mesogens) have begun to appear in recent years, such as bent-core "banana" molecules and dimers, which exhibit novel and potentially valuable properties. This work will focus on fundamental questions of how dimers can be designed to possess the required liquid crystal phase sequences and what the general structure-function rules for these new molecules are. The objectives are to synthesize a series of readily accessible dimers, control their mesogenicity by the modification of tails and cores, construct "structure-property" relationships in this new type of mesogens, and find suitable alignment techniques.The ultimate anticipated benefits include the development of a new type of electro-optic (EO) materials that will surpass current organic competitors in EO strength and lifetime, and will surpass current commercial EO materials in EO performance, integrability, and low cost. Potential commercial applications include telecommunications (high-speed EO modulation (e.g. 100GHz), M by N switches, free space communications beam steering, amplification), detection (LADAR beam steering, optical sensors), and optical information processing (spatial light modulators, holography, optical computing and storage).

这个小型企业创新研究(SBIR)第一阶段项目旨在测试开发提供以前无法获得的材料性能的复杂液晶分子系列的可行性，特别是先进的电光性能。几十年来，占主导地位的液晶分子一直是简单棒形状的变体。近年来，一些全新的液晶分子(介元)开始出现，如弯曲核心的“香蕉”分子和二聚体，它们显示出新的和潜在的有价值的性质。这项工作将集中在基本问题上，即如何设计二聚体以具有所需的液晶相序列，以及这些新分子的一般结构-功能规则是什么。目标是合成一系列易于获得的二聚体，通过修饰尾部和核心来控制它们的介晶性，在这种新型介元中构建结构-性质关系，并找到合适的对准技术。最终预期的好处包括开发一种新型的电光材料，这种材料在电光强度和寿命方面将超过现有的有机竞争对手，在电光性能、可积性和低成本方面将超过现有的商品化电光材料。潜在的商业应用包括电信(高速电光调制(例如100 GHz)、M x N开关、自由空间通信波控、放大)、检测(LADAR波控、光学传感器)和光信息处理(空间光调制器、全息术、光计算和存储)。
