St. Wu et al., HIGH BIREFRINGENT LIQUID-CRYSTALS, Molecular crystals and liquid crystals science and technology. Section A, Molecular crystals and liquid crystals, 261, 1995, pp. 79-86
Several liquid crystal dyes and fluorinated compounds with high birefr
ingence are synthesized and their properties evaluated. These polar co
mpounds are useful dopants for enhancing the dielectric anisotropy of
the dialkyl diphenyl-diacetylene host.
