Four azo-Schiff base liquid crystalline compounds with different polar groups named (A1S, A2S, A3S, A4S) have been synthesized and their structures were characterized by using (FTIR) spectrometry technique the peaks in the infrared spectrum matched the literature in diagnosing the functional groups while their liquid crystalline phase transition and temperature range was confirmed by differential scanning calometery (DSC) which indicate the presence of liquid crystalline phases, The textures of the synthesized liquid crystalline compounds were performed using polarized optical microscope which show a nematic phases in the (A1S) and (A3S) compounds .
