Mesomorphic Phenyl Benzoate and 1,3-Dioxane Derivatives Bearing Terminal Vinyl Group
4-Alkylphenyl 2-chloro-4-(4-vinylbenzoyloxy) benzoates and 2-phenyl-1,3-dioxane derivatives with terminal vinyl groups were synthesized.Most of the novel compounds obtained possess characteristic mesomorphic ranges.
Liquid crystalline materials comprised of substituted phenyl p-benzoyloxybenzoates are useful in electro-optical elements. These materials have low crystal to mesophase transition temperatures and have a broad mesophase temperature range.
