W-shaped mesogens and variations of their molecular structure
Original language description
New bent-core liquid crystalline dimers with W-shape molecular geometry have been prepared and studied. We have modified dimer shape by variation of the connecting part between two bent-core units and changing the terminal chains (perfluroalkyl, siloxanealkyl). Additionally, we have altered the inner bend angle value (120°, 60°, and 148°) by utilization of different aromatic units. Mesomorphic properties of new dimers were established based on the texture observation in the polarizing microscope and DSC measurements. Moreover, x-ray structural analysis has been performed for selected dimers to confirm phase identification. For most of the studied dimers nematic or columnar phases has been detected, for several compounds appearing in a nematic-columnar phase sequence on cooling from the isotropic phase. We have tried to generalize and compare presented data with corresponding monomers and previously studied dimers.n
