Paper Abstract
We describe a distinct polar nematic liquid crystal formed from the polar rod-like aromatic polyester which comprises 4-hydroxybenzoaic acid (HBA) and 6-hydroxy-2naphthoic acid (HNA) in a molar ratio of 73/27. The nemtic liquid crystal is biaxial and the polarity appears along both axes as determined by measurements of the second harmonic generation. The polar structure disappeasrs when the molecular weight in polyester is decreased, showing that the large dipole moment of each chain is responsible for the polar ordering. The strong dipole-dipole interaction between polar rod-like molecules may be ascribed to the origin of the polarility.
