THERMOTROPIC LIQUID CRYSTAL BEHAVIOR IN SOME AROMATIC ESTERAMIDES.

Article abstract of DOI:10.1080/00268948208071024

Ester-amide analogs of p-phenylene di-p-substituted benzoates have been synthesized and the thermotropic liquid crystal properties of the two series are compared. The crystalline, smectic, and nematic phases are all more thermally stable in the ester-amides than in the diesters. In the corresponding series of 4-alkoxybenzoyl compounds, as the alkyl chain length increases the difference in nematic phase stability also increases, but the difference in smectic phase stability decreases. Introduction of a methyl substituent into the central ring reduces the stability of all three phases, and increases the sensitivity of smectic phase stability, but not of crystalline or nematic phase stability, to alkyl chain length.
