Abstract

Most of the past research in nematic liquid crystals has concerned itself with the synthesis of compounds possessing a high nematic thermal stability. However, we have continued and directed our investigation toward the preparation of low molecular weight Schiff’s bases in order to depress the nematic-isotropic transition point. This work has led to the discovery of the alcohol function as a terminal group in nematic liquid crystals, and in particular, to materials possessing low crystal nematic transitions.
