摘要:The synthesis of Schiff base - N,N’-bis-[4-(4’-octyloxy-benzoic)-ester-benzyliden-n-propyl]-piperazine (4) in a multistep process is repported. The last step involves the condensation of 4-octyloxy-benzoic acid 4-formyl-phenyl ester aldehyde (3) with 1,4- bis(3-aminopropyl)piperazine. The intermediates as well as the product were characterized by elemental analysis, melting point and IR, 1H and 13C-NMR spectroscopies. The potential mesogenic property of (4) has been checked with a polarising microscope equipped with a heating stage.
