In this project, liquid crystals are to be combined with the self-organized nanoporosity in solids of silicon, quartz glass and anodically oxidized aluminum (AA0) to design optical materials with adjustable and switchable linear and circular birefringence. Thermotropic chiral and achiral systems of rod and disc-shaped molecules are investigated as liquid crystalline systems. On the one hand, the fundamental understanding of the self-assembly of these mesogens in porous media will be expanded. On the other hand, it will be investigated from a materials science point of view how porosity on the meso- and macroscale in solids can be combined with soft matter to produce mechanically robust 3-D photonic metamaterials.

在该项目中，液晶应与硅，石英玻璃和阳极氧化铝（AA0）的固体中的自组织纳米质量结合使用，以设计具有可调节且可调节的线性和圆形双重折射的光学材料。研究杆和圆盘形分子的热性手性和精神系统作为液晶系统。一方面，将扩大对这些中质媒体中这些中元的自组装的基本理解。另一方面，将从材料科学的角度研究它如何与软物质结合使用固体中的孔隙率，以产生机械强大的3-D光子超材料。
