Abstract

Many ether-hetero cyclic and amide-heterocycls compounds synthesized in our work by using condensation reaction, cyclization reaction, ring closure reaction, some them alkylation to form ether terminal with various starting materials and various conditions. All reactions followed by using (TLC-plate). The structures of the newly liquid crystals were characterized by using chemical techniques ((FT. IR, 1H.NMR) with several studies represented by ((liquid crystal phase by using polarized optical microscope technique, DSC-Analysis, other chemical studies, some physical characterization, chromatographic studies)).
