Dopant-Enhanced Vertical Alignment of Negative Liquid Crystals

A simple method for achieving high-contrast vertical alignment of high birefringence (Dn 0.28) negative dielectric anisotropic liquid crystal mixture using buffed polyimide substrates is demonstrated. By doping a positive, or non-polar dielectric anisotropic compound or mixture to the laterally difluorinated tolane liquid crystal host, an excellent vertical alignment was obtained. This alignmen...

Liquid crystals carrying stereodefined vicinal difluoro- and trifluoro- alkyl motifs.

The synthesis of the stereospecifically fluorinated difluoro- and trifluoro- rac-3 and rac-4 is described where the fluorine atoms are positioned adjacent/vicinal to each other and the physical characteristics of these candidate liquid crystals including negative dielectric anisotropy are measured and rationalised.
