Abstract


These research includes synthesis of two series of Schiff bases differ in the type of terminal group, where one of them has a terminal carboxyl group COOH   while the other contains methoxy  OCH3  as a terminal group. 

In the first part of this  research it was Identification by spectroscopy methods using infrared IR and nuclear magnetic resonance H NMR spectrum, besides elemental analysis shows the exact chemical structure of the expected synthesized compounds. 
In the second part was the study of liquid-crystalline behavior by polarized optical microscopy  POM and differential scanning calorimetry DSC that  showed a liquid crystal phase in the compounds that has odd number of carbon atoms in the terminal chain compounds in the first series, while the second series compounds showed liquid crystal phase in the   compounds that containing even number of atoms of carbon in the terminal chain. 
Keywords: chain , series , liquid.
