    Helical twisting power and compatibility in twisted nematic phase of new chiral liquid crystalline dopants with various liquid crystalline matrices

  • Original language description

    Chiral dopants exhibiting smectic phases were prepared and their helical twisting power (HTP) and thermal phase behaviour in mixtures with LC hosts were studied. The influence of host LC on HTP was evaluated and generally higher values were found for hosts with high birefringence. High enhancement was found for LC-chiral dopant pair both having similar aromatic core. Chiral dopants exhibited limited compatibility with LC hosts in twisted nematic phase at room temperature. For one mixture, single twisted nematic phase with selective light reflection band with maximum at wavelength about 1.0 µm was obtained. Carboxylic acid dopants exhibited total compatibility with the host in single twisted nematic phase at elevated temperatures, allowing preparation of mixtures with reflection band in the visible range, blue phases were observed, too. Intermolecular hydrogen bonding between acid proton and pyridine nitrogen of dopants was found.
