Abstract: A heterocycle, 4-[(1,3-benzothiazol-2-ylimino)methyl]phenyl dodecanoate, was
synthesized and its IR, 1H NMR, 13C NMR, elemental analysis and MS spectroscopic data
are presented. This new compound exhibited smectic A phase.
Keywords: 4-[(1,3-benzothiazol-2-ylimino)methyl]phenyl dodecanoate; heterocyclic
liquid crystal; smectic A
Schiff bases have attracted much attention ever since the discovery of the first room temperature
liquid crystal, 4-methoxybenzylidene-4’-butylaniline [1]. Many kinds of heterocyclic structures, such
as pyridine [2], furan [3], thiophene [4] and benzothiazole [5–7] have been introduced as core centre in
liquid crystalline compounds. In this paper, we report the synthesis of a new Schiff base comprising
the benzothiazole moiety: 4-[(1,3-benzothiazol-2-ylimino)methyl]phenyl dodecanoate. This new com-
pound exhibits enantiotropic smec
