STTR Phase I: High Twisting Power Chiral Materials for Nanostructured Bragg Reflective Displays

第一阶段的小企业技术转让（STTR）项目旨在调整手性溶质的分子结构，使其适用于布拉格反射式手性液晶显示器。 这需要一种分子设计，其将在纳米相的温度范围内保持相同的纳米结构尺寸。 当将手性溶剂加入到手性液晶中时，就会产生螺旋纳米结构。 该建议利用了最近发现的一类新的具有超高螺旋扭转力（HTPs）的可溶性手性分子。 只有3个wt。需要在光致抗蚀剂基质中占材料的50%的材料来产生介电分层堆叠以布拉格反射可见光。 本工作的技术突破是研制出性能大大改进的反射显示材料。 高HTP材料将提供：显著更低的电压、更快的开关特性、改进的电光响应、更亮和更高对比度的显示器，并且将避免外国拥有的专利，这些专利禁止美国制造商结合目前制造手性反射显示器所必需的多种手性材料。

This Phase I Small Business Technology Transfer (STTR) project aims to make adjustments in the molecular structure of the chiral solute to make it suitable for application in Bragg reflective chiral nematic high resolution displays. This requires a molecular design which will maintain the same nanostructure dimensions over the temperature range of the nematic phase. Helical nanostructures are created when a chiral solvent is added to a nematic liquid crystal. This proposal takes advantage of the recent discovery of a new class of soluble chiral molecules which possess ultra-high helical twisting powers (HTPs). Only 3 wt. percent of the material in a nematic host is required to create a dielectric layered stack to Bragg reflect visible light. The technical breakthrough of this work is to develop greatly improved reflective display materials. The high HTP materials will provide: significantly lower voltage, faster switching characteristics, improved electro-optic response, brighter and higher contrast displays, and will avoid foreign owned patents which prohibit US manufactures from incorporating multiple chiral materials currently necessary for making chiral nematic reflective displays.
