Estimation of Nematic-Isotropic Points of Nematic Liquid Crystals

Abstract

Abstract A survey has been made of reported nematic-isotropic points of nematic liqid crytals having the following structure: where X and Z are: R-, Ro-, RCO2-, ROCO2-, RCO-,ROCO-; R is n-alkyl varying form C1 to C6; andy is: The variation of the nematic-isotropic points with structure is sufficiently regular to permit the generation of sets of parameters for X, Y and Z that can be used to make resonable predictons of the namatic-isotropic points for all combinationf of X, Y and Z.
