Abstract

Three and four ring liquid crystalline compounds containing two flexible ethane groups or two carboxylic groups and benzene, biphenyl, cyclogexane and bicyclo (2,2,2) octane rings were synthesized and their phase transition temperatures and enthalpies were measured by a DSC calorimeter. These compounds were tested as components of mixtures for display applications. It was found that the diethane compounds, when mixed with two-ring isothiocyanates, form low viscosity mixtures with a broad range of the nematic phase suitable for the TN mode and the diesters form mixtures which are suitable for the STN mode.
