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.

在这个项目中，液晶将与硅，石英玻璃和阳极氧化铝（AA 0）固体中的自组织纳米孔隙相结合，以设计具有可调节和可切换的线性和圆双折射的光学材料。热致手性和非手性系统的棒状和盘状分子的液晶系统进行了研究。一方面，这些介晶在多孔介质中的自组装的基本理解将扩大。另一方面，将从材料科学的角度研究固体中的介观和宏观尺度上的孔隙率如何与软物质相结合，以产生机械鲁棒的3-D光子超材料。
