Effects of Certain Central Groups on the Liquid Crystal Properties of Dicarboxylic Esters
At present there is no useful theory in the field of liquid crystals which allows the prediction of whether a given molecule will show, for example, a smectic or nematic mesophase and what the thermal range of the mesophase will be. All nematogenic compounds to date which are useful in electronic display devices contain para-alkoxy/alkyl-substituted benzene rings held together by a central group containing Π-electron density. For the past few years we have been carrying out heuristic investigations on the. effect of different central groups on liquid crystalline behavior. In this paper we report some recent results.
