Our research aims for the design of novel liquid crystalline (LC) materials consisting of compounds with non-conventional shapes such as stars, V- or board-shaped molecules. The star topology is generated by symmetric attachment of three to six arms to a core unit. We achieve the control of the self-assembly in LC materials by the variation of the core, the arm scaffold and the peripheral chains. Detailed understanding of the stacking procedures in the solid-state by nanosegregation and space-filling allows the incorporation and positioning of functional building blocks. This converts the compounds on complex functional LC materials, which can be applied in organic electronics. Board- and V-shaped mesogens are investigated with respect to the formation of the highly elusive biaxial nematic mesophase. Biaxial nematogens are proposed as new materials for the future fast-switching LC-displays.
