Clarke, MJ and Blatch, AE and Coles, HJ (2005) The effects of introducing ester linking groups on the flexoelectro-optic properties of symmetric bimesogens. Molecular Crystals and Liquid Crystals, 434. ISSN 1542-1406Full text not available from this repository.
In the chiral nematic phase, flexoelectricity can give rise to an interesting electrooptic switching effect, known as flexoelectro-optic switching. Flexoelectro-optic switching gives a fast v-shaped switching regime. Previous studies show that symmetric bimesogens are particularly suited for flexoelectro-optic switching. By introducing two ester linking groups into the molecular structure of a symmetric bimesogen, it was hypothesised that the flexoelectric properties will be enhanced significantly because of the resulting increase in the dipole moment of the molecules. This was found to be the correct; however, the inclusion of ester linking groups reduced the liquid crystallinity of the material.
