SYNTHESIS AND CHARACTERIZATION OF LIQUID-CRYSTALLINE MOLECULES CONTAINING THE QUINOLINE UNIT

A homologous series of heterocyclic liquid crystals containing the qui noline unit have been synthesized and characterized. These compounds s how a smectic phase at low temperatures. The quinoline unit containing lone pair electrons introduces a significant dipole moment resulting in attractive forces to form a smectic phase. The heterocyclic structu re map also break the centrosymmetry of the core of the molecule, whic h may be favored in the application of displays and nonlinear optics.
