Abstract
Several laterally difluorinated tolane and diphenyl-diacetylene liquid crystals were synthesized and their physical properties evaluated. Th ese compounds exhibit low melting temperature, small heat fusion entha lpy and large negative dielectric anisotropy. Their potential applicat ions are in the high contrast displays using a homeotropic cell and fo r infrared spatial light modulators.
