Diluters' effects on high n and low-viscosity negative epsilon terphenyl liquid crystals
Lateral difluoro terphenyls exhibit a high birefringence, fairly low viscosity and modest dielectric anisotropy, but their alignment in a vertical alignment (VA) cell often deteriorates at elevated temperatures if their concentration is high. We have studied the effects of six diluters for lowering the viscosity while stabilizing the VA of the terphenyl host mixture at elevated temperatures. The pros and cons of each diluter are analysed.
