A new group of liquid crystal materials with sulphur atoms incorporated in the principal structure
Abstract
2-(p-Alkoxyphenyl)-5-alkyl-1,3-dithians and -1,3-oxathians, sythesized by the acetal-formation procedure, form mesomorphic phases with the lowest TC – N at 37 °C and the highest TN – 1(but not for the same members of these series) at 81 °C; these compounds therefore constitute a new group of liquid crystal compounds with sulphur atoms incorporated in the principal structure.
