Nematic phases of disc-and rod-shaped molecules
Substantial effort has been made to prepare mixtures of disc-shaped and rod-shaped mesogens, since these mixtures provide one of the requirements in one of the routes towards biaxiality in nematic mesophases. We present the synthesis and mesomorphic properties of two novel liquid crystals based on a disc-shaped mesogen and multiple rod-shaped mesogens. The materials show enantiotropic nematic phases and mixing studies point out that the linked disc-rod mesogens are miscible with both the disc-shaped and the rod-shaped precursors.
