- Influence of fluoro substituents on the mesophase behaviour of banana-shaped molecules
-
Three new series of bent-shaped five-ring liquid crystals, based on the ester of isophthalic acid as the central core and azomethine linkages, are presented. They differ by the number and the position of halogeno substituents on the outer rings. This lateral substitution strongly influences the type of mesophases formed. Calculations were performed to determine the modification of the distribution of charge along the different molecules.

- Novel halogen-containing ester compounds, and their intermediates, and method of producing the same as well as liquid crystal compositions containing the same and light switching elements
-
This invention provides a novel halogen-containing ester compound represented by the following general formula (I): STR1 (wherein R is an alkyl group, A is selected from a single bond, --O--, --COO-- and --CO--, both of X and Y are halogen atoms or either one of X and Y is a halogen atom and the other is a hydrogen atom, each of m and n is 0 or 1, m+n=0 or 1, each of k and l is an integer of 1 or more, provide kl), a liquid crystal composition and a light switching element each containing the above compound as well as a novel fluorophenol compound represented by the following general formula (II): STR2 (wherein each of k and l is an integer of 1 or more, provided kl) as an intermediate for the synthesis of the above ester compound and a method of producing the same.
