Synthesis and Some Physical Properties of Bicyclohexanes Having Fluoro Substituted Alkyl Moiety
摘要:
The influence of introducing fluorine atoms into alkyl chains of dialkylbicyclohexanes on their physical properties has been investigated. Wide mesophase ranges of the bicyclohexanes were induced by the fluorine atoms. Their viscosity changed depending on the position of fluorine atoms on the alkyl chains and some of the fluorinated bicyclohexanes showed low viscosity. Also dielectric anisotropy and birefringence increased by introducing fluorine atoms. By using the fluorinated compounds mixtures for TFT and STN applications having attractive properties; a wide mesophase range, lower viscosity and higher specific resistivity could be obtained.
