Cyclobutanecarboxylic acid derivatives and liquid crystalline compositions containing them

An optically inactive cyclobutanecarboxylic acid derivative of the general formula STR1 wherein R1 is a hydrogen atom or a straight or branched chain alkyl group having 1-14 carbon atoms, R2 is a straight or branched chain alkyl grou

LIQUID CRYSTAL MATERIALS WITH SULFUR ATOMS INCORPORATED IN THE PRINCIPAL STRUCTURE: 1. NEW LIQUID CRYSTAL COMPOUNDS WITH 1,3-DITHIANE RING.

2-(p-Substituted phenyl)-5-alkyl-1,3-dithianes, new liquid crystals, were synthesized by the thioacetalization of the corresponding aldehydes and dithiols. These compounds have characteristic supercooling states, exhibit monotropic liquid crystal phases even in the case of long terminal alkyl substituents. The mesomorphic characteristics of these compounds were different from those of the corresponding 1,3-dioxanes, this must originate in the difference in the molecular width caused by the difference in the atomic volume between sulfur and oxygen.
